Could a larger capacitor, at the output of the SMPS, destroy components with larger current draw when its being charged?
https://electronics.stackexchange.com/questions/383325/could-a-larger-capacitor-at-the-output-of-the-smps-destroy-components-with-lar
Since I have a bunch (>100pcs) of 100uF, 16V, electrolitic caps laying around, I would like to use them to store a of bit current at the exit of thesse two switching converters.
I understand that using a big capacitor is better if you have an instant and huge current need, but I do not know what happends when you start everything up.
Would a 100uF electrolitic capacitor draw an extremly high current at startup, as all capacitors do when they are being charged up and therefore would it destroy the IC or the inductor or would it be just fine because it’s only high current for a fraction of a second?
No the IC would protect itself and, in addition, the LT8364 has a programmable soft-start option:
For the TPS62125, if you read the data sheet it tells you that there is internal current limiting circuit (max 900 mA) – see page 5 of the data sheet – this is to prevent the inductor going into saturation primarily but serves the purpose you appear to want.
There is also a 200 us output voltage ramp time to reach 1.8 volts and this means that dV/dt = 9 V / ms so, if the capacitor is (say) 100 uF, the current cannot be higher than 0.9 amps (coincidentally as per the current limit circuit).
Most integrated converters have soft-start and/or cycle-by-cycle current limit. So in general no, nothing will be destroyed with large output capacitance. (Read the datasheet.)
However, that doesn’t mean that the converter will be stable or have good performance. You should check the datasheets for the parts to see how to select the appropriate amount of output capacitance AND then do some testing to see how it performs.
The exception may be the boost converter where inrush flows directly through the inductor and diode or sync FET to the output caps. In that case depending on the component ratings you could conceivably damage components. If not from the inrush sometimes from the converter starting while the inductor is still saturated from the inrush. This is common in PFC boost converters.
Could a larger capacitor, at the output of the SMPS, destroy components with larger current draw when its being charged?

Making Zero the Hero in AC-DC Conversion
Oct. 4, 2022
Zero voltage switching in power-conversion applications holds the key to efficiency improvements. Here we look at how ZVS-based designs can deliver those improvements across the widest possible load range.
https://www.electronicdesign.com/power-management/whitepaper/21252055/eggtronic-making-zero-the-hero-in-acdc-conversion?utm_source=EG+ED+Analog+%26+Power+Source&utm_medium=email&utm_campaign=CPS220929075&o_eid=7211D2691390C9R&rdx.identpull=omeda|7211D2691390C9R&oly_enc_id=7211D2691390C9R
What you’ll learn:
ZVS and its benefits.
New power-conversion architectures that optimize efficient power conversion by supporting ZVS soft switching.
In recent years, the discussion has grown about zero voltage switching (ZVS) as the ideal route to increase the efficiency of ever-higher-frequency ac-dc power-conversion designs without impacting EMI performance. However, achieving such “soft” switching is difficult, especially across the varying range of loads and input and output voltages that are now common in applications such as universal USB chargers.
Many conventional LLC converters, for example, use resonant ZVS to achieve high efficiencies at high and full loads for a given input voltage. Unfortunately, they suffer as the load reduces or the input voltage changes, and hard switching losses start to become more prevalent.
This article explores ZVS and its benefits and look at the challenges of delivering ZVS in conventional ac-dc conversion applications. It also introduces techniques that “flatten” the efficiency curve by enabling ZVS soft switching across a much wider load range and input and output voltage ranges, with practical examples.
Hard switching has a number of downsides, including the energy dissipation, the stress put on the MOSFET, and the EMI generated, which is proportional to the voltage across the MOSFET (VDS) and the switching frequency.
Quasi-resonant (QR) flyback converters go some way to minimizing the losses and reducing EMI by ensuring that the turn-on occurs when VDS is at a minimum—or in a “valley”—hence the name “valley switching.” At full load and with U.S. input voltage, the QR flyback has excellent performance, as it’s almost ZVS. However, in other working conditions, the valley is too far from zero, and it incurs hard-switching losses.
Soft-switching (or ZVS) techniques are able to ensure that switching only occurs when VDS = 0. In this approach, the MOSFET turn-on transition losses (which are the most critical losses) are zero, irrespective of the operating frequency and input voltage.
Soft switching significantly improves efficiency and brings other benefits such as elimination of COSS discharge losses and high peak currents. The gate drive also is somewhat simplified as there are no “Miller” effects. Another possible enhancement is the addition of an regenerative clamp that can be used to recover energy from leakage inductance, while also suppressing voltage spikes on the main MOSFET.
With the huge breadth of power requirements, it’s important that the solution is tailored to the application. Relatively small differences in requirements can lead to significant differences in results.
New Ways to Implement ZVS
One example of the latest methods that’s being used to address ZVS is the EcoVoltas family developed by Eggtronic. It maximizes efficiency across the load range while minimising standby power consumption, facilitating the ability to meet modern efficiency requirements.
To address higher-power applications that require front-end power factor correction (PFC), Eggtronic’s SmartEgg (Fig. 1) is a single-stage PFC + ac-dc converter that acts simultaneously as a PFC and isolated regulator. A traditional approach requires three stages (boost PFC, dc-dc buck, and resonant LLC), so the removal of one stage immediately provides efficiency gains. SmartEgg is suited to applications in the 100-W to 1-kW range, including high performance laptops, TV panels, and home appliances.

How to Overcome the Limits of Boost Converters
Oct. 5, 2022
When designing and evaluating boost converters, sometimes the intended output voltage isn’t realized. Instead, it has a lower value than desired.
https://www.electronicdesign.com/power-management/whitepaper/21252189/analog-devices-how-to-overcome-the-limits-of-boost-converters?utm_source=EG+ED+Analog+%26+Power+Source&utm_medium=email&utm_campaign=CPS220929075&o_eid=7211D2691390C9R&rdx.identpull=omeda|7211D2691390C9R&oly_enc_id=7211D2691390C9R
What you’ll learn:
The impact of voltage gain on boost converters.
The roles played by an inductor’s load resistance and DCR.
Boost converters are used to generate high output voltages from low input voltages. Such a voltage conversion can easily be done with a switching regulator that has a boost topology. However, the voltage gain has a natural limit: The voltage gain is the ratio of output voltage to input voltage. If 24 V is generated from 12 V, then the voltage gain is 2.
To generate a high voltage, the duty cycle increases to values close to 1, but they never reach 1.
By selecting a boost converter with a high maximum duty cycle, it may seem possible to generate a high output voltage from a low supply voltage. However, there’s more to it than that. Besides the duty-cycle limits, the maximum possible voltage gain also must be considered.
In conclusion, the design of a circuit with a boost topology must always include determination of the maximum possible voltage gain. Interestingly, this depends on the load resistance—i.e., the output current—and the DCR of the inductor. If it turns out that a required voltage gain doesn’t seem possible, a larger inductor with a lower DCR can be selected.

Novel Flyback-Based Switching Architecture Offers Efficient Alternative to LLC Converters
Oct. 10, 2022
Delivering a lower-cost, higher-efficiency option, Pulsiv’s new converter targets 100- to 250-W applications but could scale higher to support 10 kW or more.
https://www.electronicdesign.com/power-management/whitepaper/21252461/electronic-design-novel-flybackbased-switching-architecture-offers-efficient-alternative-to-llc-converters?utm_source=EG+ED+Analog+%26+Power+Source&utm_medium=email&utm_campaign=CPS221006038&o_eid=7211D2691390C9R&rdx.identpull=omeda|7211D2691390C9R&oly_enc_id=7211D2691390C9R
Pulsiv, a Cambridge-based startup, announced its new power electronics technology that uses a unique algorithm-based switching technique to convert ac to dc. Now, low-cost flyback architectures can be used at power levels well above the 70- to 80-W limit, which usually requires more complex and costly resonant converters.
The inductor-less switching architecture eliminates the need for a conventional boost/PFC stage, allows for the use of lower-cost components, and maintains high efficiency down to as low as 2% of rated load (85% at 1%). Furthermore, it eliminates the need for a low-power standby supply for most applications. While the initial reference designs target applications in the 100- to 250-W range, Pulsiv said the technology can be scaled to support much larger applications of 10 kW or more.
Branded as the Pulsiv OSMIUM switching architecture, it performs highly efficient ac-dc conversion using an application-specific MCU to control two power switches (S¹ and S² in Fig. 1). The switches alternately charge and discharge a small storage capacitor according to an algorithm that smooths inrush and output currents.
To demonstrate the technology’s advantages, Pulsiv designed a universal-input, single-switch, 150-W flyback power-supply design that delivers 97.5% average (99.5% peak) front-end efficiency while maintaining 90% at just 2 W (Fig. 3). A 240-W interleaved flyback is currently being developed and work is underway to showcase reference designs with even higher power capability.
Since the OSMIUM microcontrollers (PSV-AD-150 and PSV-AD-250 sampling now) don’t directly determine output power, they can be used as a platform for any application requiring 1 W to 10 kW by adjusting only three system components and connecting a suitable dc-dc converter. In addition, the architecture can be combined with commodity flyback dc-dc converters to serve as a lower-cost alternative to LLC solutions.
Engineering samples of the OSMIUM microcontrollers will be available through a network of distribution partners. Pulsiv also will be offering the PSV-AD-250-DS development system that can be used by engineers to evaluate the technology. All that’s required to produce a complete power-supply prototype is to add a suitable dc-dc converter.

New 400 kHz Current Sensors Enable More Sustainable Designs in Switch-Mode Power Designs
https://www.allegromicro.com/en/insights-and-innovations/technical-documents/acs37002?utm_source=electronicdesign.com&utm_medium=referral&utm_campaign=Personif.ai&utm_term=&utm_content=pcb-current-sensing
Driven primarily by cost and shrinking PCB area, system designers are opting for smaller passive components and up-integrated sensor solutions in their switched-mode power designs. The space savings of smaller capacitors and inductors comes at the expense of efficiency in the form of switching loss, as higher switching speeds are required to generate an equivalent level of power.
The availability of wide bandgap devices (SiC, GaN, and GaAs) has reduced the impact of switching losses on efficiency. As such, switching frequencies are on the rise in many power applications, including DC to DC converters, solar MPPT and inverters, telecom and server power supplies, power distribution units (PDUs), uninterruptible power supplies (UPS), and charging stations.
With these new gains in efficiency and space savings, the high-speed trend is expected to continue, creating new requirements for current monitoring and protection. Allegro’s broad family of integrated Hall-effect current sensor ICs have kept pace with this high-speed trend by offering innovative high-speed solutions without sacrificing on size, efficiency, or performance.

How [NOT] to MAX test a power supply!
https://www.youtube.com/watch?v=hYLUN5zZcA8
How hard can it be to max power test a power supply? After finding out my laboratory power supply will deliver more volts than advertised, I have decided to test how many watts it will deliver. The issue is that I don’t know how? In this video, I will give it some attempts and learn from the mistakes… Will the power supply deliver the watts it is supposed to?
