Power electronicsin general is a technology that deals with conversion of electrical energy by electronic circuits. A unit that perform such conversion is known as power supply unit, or PSU. Technically speaking, of course, a PSU does not "supply" power. It just converts it from one form (such as AC) into another one (such as DC) and changes its characteristics as required. Power electronics originated about a century ago. Originally it started with the application of grid-controlled gas-filled tubes for power control. The subsequent development of SCR, bipolar transistors and especially high-voltage MOSFETs really revolutionized the industry and resulted in rapid expansion of various power electronic applications.This site is a power supply/ power electronics information resource. Here you can find general reference information, schematics, electronics calculators, as well as engineering career resources. |
