Grid tie inverter technology

A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, normally 120 V RMS at 60 Hz or 240 V RMS at 50 Hz. Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine, hydro-electric, and the grid. They range from small

Sine wave inverter technology

An ideal power inverter will produce same kind of power that is available from mains outlet, which typically means sine waveform 60 Hz 11-120V AC or 50 Hz 220-240V AC. That kind of power source can power all mains powered devices as long as enough power is available. Where power inverter devices substitute for standard

Modified sine wave inverters

This is a continuation to my Power inverter designs post. The first post was about general details of inverters and square wave inverters. Because square wave inverters are not suitable for many applications. The next better inverter category is so called modified sine wave inverter. Modified sine wave inverters are less complicated than sine wave

Power inverter designs

A power inverter, or inverter, is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The inverter does not produce any power; the power is provided by the DC source. This document is collection of information on power inverter technology and gives links to DIY circuits – both good

Under the 110 kV power line

Radiation is the emission or sending out of energy from any source. Generating, transmitting, distributing, and using electricity all expose people to ELF radiation. Power lines, household wiring, and any device that uses electricity can generate ELF radiation. How much electromagnetic radiation you are exposed to depends on the strength of the electromagnetic field, your

Linear power supply rectifier designer

LINEAR POWER SUPPLY DESIGN ASSISTANT #1 at https://www.changpuak.ch/electronics/power_supply_design.php is a tool for designing and simulating linear power supply rectification and smoothing capacitors See the circuit diagram. Enter the design data and can see the output voltage ripple and current on circuit. You can try with different capacitor values, different loads and different transformers. This is

Mains surge suppressor teardowns

I saw a request for circuit diagram in Facebook electronics group: Hello feds. Required surge protector circuit. Working on 220v. 50hz 10amps load. I first offered this reverse engineering of one commercial mains surge protector “Ahlstrom 23 368″. The manufacturee component codes of the exact components used. S20K250 is a varistor for 250V AC /
