In high-voltage switching power supply, it cancels power frequency transformer with isolation effect, and it isshown in the diagram. It is simplified principle diagram of switching power supply which is non-isolation with network. Switching tube VT1 is connectedto network through rectifier, the switching tubehas electrification. Switching tube can couple the energy to output end through high-frequency transformer. Because output end and input end have the same earth point andare directly connected with error amplifier VT2 connected in output end and switching tube VT1, output end is breaking over with network through output end.
