Abstract: Disclosed in the present invention are a self-excited push-pull converter circuit, a related power supply module, and a related power supply system. The self-excited push-pull converter circuit has its start capacitor changed into two capacitors connected in series and decreasing in capacitance as the terminal voltage increases; when one of the capacitors is short-circuited, the other capacitor would decrease in capacitance because of the increase in working voltage, and thus, the capacitance actually provided by the other capacitor is not significantly different from the capacitance provided when the two capacitors connected in series are normal. The present invention can cause the failure rate caused by the start capacitor to be the square of the original failure rate, can easily solve the technical problem of high product failure rate due to capacitor failure in combination with an input filter capacitor and an output filter capacitor which are placed externally, and can also reduce product models and increase the universality in use for customers by further placing an output rectifier circuit externally.
