Beschreibung
Zusammenfassung:	The invention discloses a multi-level output inverter circuit system and a power supply circuit. The system comprises a first-stage inversion module and a second-stage inversion module, the first-stage inversion module is used for inverting the voltage of the direct-current voltage source into a first-stage output voltage and outputting the first-stage output voltage to the second-stage inversion module; wherein the voltage of the direct-current voltage source is Vdc, and the first-stage output voltage comprises Vdc, 2Vdc and 3Vdc; the second-stage inversion module comprises n switched capacitor units, and n is greater than or equal to 1; the second-stage inversion module is used for inverting the first-stage output voltage into a second-stage output voltage and outputting the second-stage output voltage from a third end and a fourth end of the second-stage inversion module; wherein the second-stage output voltage comprises a plurality of output levels. The inverter circuit system has the advantages of being
