Using a supercapacitor for power management and energy storage in IoT–Part-1 The environment has abundant energy but little power. Energy harvesting can tap the environment’s “infinite” source of energy, and avoids the cost of wiring to mains power or replacing of batteries. This article will look at using small solar cells.  Depending on the light level, whether indoors or out, small solar cells may deliver

Power Integrations highlights importance of power factor correction at APEC 2017 | EDN–at-APEC-2017?utm_content=bufferce187&utm_medium=social& Power factor correction is the process of improving a low power factor in a facility by increasing the ratio of real (working) power to apparent (total) power. Power-factor correction allows the input current to continuously flow, reduces the peak input current, and reduces the energy loss in the power supply, thus improving its operation

How Deadly Is Your Kilowatt? We Rank The Killer Energy Sources Everyone’s heard of the carbon footprint of different energy sources, the largest footprint belonging to coal because every kWhr of energy produced emits about 900 grams of CO2. Wind and nuclear have the smallest carbon footprint with only 15 g emitted per kWhr. But how dangerous different energy sources are for people working with

Direct-Current Microgrids to Solve Power Woes

Innovative Direct-Current Microgrids to Solve India’s Power Woes – IEEE Spectrum article tells that a group at the Indian Institute of Technology (IIT) Madras in conjunction with industrial partners, relies on solar-powered direct-current (DC) microgrids. For homes not connected to the grid, a 125-watt microgrid can serve as the sole source of electricity. For connected
