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.\ \ [Power Electronics](https://www.delabs-circuits.com/cirdir/power.html)\ \ 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. \ \ [Power Electronic Circuits](https://www.delabs-circuits.com/cirdir/power/power1.html) - Basic Power Supply Designs\ \ AC and DC voltage Regulators, Battery Backup Power Supplies. Battery Chargers, UPS and Inverters. Dual regulated Power Supplies. 5V and 12V Regulators. Benchtop Power Supplies. [Power Supplies Section](https://www.delabs-circuits.com/cirdir/power/power2.html) Switching Supplies and SMPS\ \ Circuits of SMPS, Power Supply, Switch Mode Power Supply are here.
