Power Electronics Trainer

We are offering power electronics trainer (pet)
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.
