Beschreibung
Zusammenfassung:	The invention discloses a three-phase regulated power supply for a transformer air cooling system. The power supply comprises an input rectifier transformer, a filter circuit and an inverter circuit.The input end of the input rectifier transformer is used for being connected with a three-phase alternating-current power supply. The output end of the input rectifier transformer is connected with the filter circuit, the filter circuit is connected with the inverter circuit, the output end of the inverter circuit is used for being connected with an air path system of the transformer, and the control end of the inverter circuit is connected with a single-chip microcomputer SPWM control circuit. The three-phase regulated power supply also comprises a voltage monitoring circuit. The voltage monitoring circuit comprises a voltage reduction circuit, a first AD converter and a processor, the input end of the voltage reduction circuit is connected to any two phases of the output end of the inverter circuit, the output e
