Beschreibung
Zusammenfassung:	The invention provides a power supply system which comprises a primary side circuit, a secondary side circuit, an auxiliary winding, a denial module, a control module and a controller. The auxiliary winding is magnetically coupled with the secondary side winding, comprises a first sub-winding and a second sub-winding which are connected in series, and is provided with a first pin arranged at a dot end of the first sub-winding, a second pin arranged at a dot end of the second sub-winding, and a grounding pin for electrically coupling a non-dot end of the second sub-winding to a grounding potential. The denial module receives the first auxiliary voltage and the second auxiliary voltage and outputs one of the first auxiliary voltage and the second auxiliary voltage as a selection voltage. The control module controls the rejection module to output the first auxiliary voltage or the second auxiliary voltage as a selection voltage according to the magnitude of the second auxiliary voltage. The controller is electri
