**Power Electronics Engineering** Power Electronics and Energy Management or PEEM blog of [delabs Technologies](https://www.delabs.net/) has a Focus of Power Supplies and Instruments related to Energy Testing. Power Management and Controls are also part of this blog. - Power Supplies, Energy Generation, Electrical Equipment. Here are power supply, inverter, drives, chargers and high current equipment diagrams and links. There are Mosfet and Thyristor circuits too. Power Supplies, Inverters, UPS, Chargers, Electro Plating, Precision Welding-erosion, Coating Metals and many other Processes are made of high current circuits. Even in measurement of parameters like Micro-Ohm high currents are involved. Electronic Circuits are required in such products to give control to time, current, frequency and voltage in order to accomplish with the required precision a process or job.
