| Abstract: | Both self-exciting PC switching power supply and extra-exciting PC switching power supply have a starting circuit, which is simple, but directly affects the starting of the power supply. As the component parameters in the circuit are at the critical state, the power supply starting turns to be at random. Some common starting circuits of PC switching power supply and their trouble phenomena are discussed in this paper. |
