Driver circuit principle diagram: Driver circuit of switching power supply: The main function of driver circuit is enlarge the variable width pulse output by pulse width controller forthe driver signal of high voltage power supply switching device. Driver circuit generally has theisolatingfunction. It always uses transformer coupling mode to energizethe high voltage power switching device and isolate input stage and output stage. Meanwhile it can add reverse bias when power switching device is cut off to increase the speed of cut-off device. When it drives MOSFET devices, the common driver circuit is achieved by a driver transformer.
