Beschreibung
Zusammenfassung:	The utility model provides a power tube driving circuit, a power supply system and an electronic device, the circuit comprises two power tube driving sub-circuits, a first end of a first resistor of each power tube driving sub-circuit is coupled to a first input end of each power tube driving sub-circuit, and a second end of a second resistor of each power tube driving sub-circuit is coupled to a second input end of each power tube driving sub-circuit; the second end of the first resistor is coupled to the anode of the first diode and the base electrode of the PNP triode. The cathode of the first diode is coupled to the emitter electrode of the PNP triode, the first end of the second resistor and the first output end of the power tube driving sub-circuit. The second input end of the power tube driving sub-circuit is coupled to the collector of the PNP triode, the anode of the voltage stabilizing diode and the first end of the first capacitor; the cathode of the voltage stabilizing diode is coupled to the seco
