Power electronics trainer power electronics lab is used to perform power electronics circuit experiments. It is very useful in power electronics laboratories for performing power experiments in colleges and universities. It is very for student to know about the characteristics of power electronics devices and the applications of power devices. The applications or power devices are in alarm circuit, lamp flasher, rectifiers, choppers, inverters. It is also used for commutation circuits. technical specifications dc power supply on board: : 0-15v at 150ma: 0-30v at 150maac power supply on board : 9v - 0v - 9v at 150maujt triggering circuit using scr (1 channel) on board r, rc triggering circuit on board.Scr control circuit provided on board for ujt firing circuit.Power devices : mosfet-irf540, ujt-2n2646, diac-db3, triac-bt136, scr-tyn604.Circuit components on board: 2 nos.
