Inverter circuit

The embodiment of the utility model relates to the technical field of electronic power, and discloses an inverter circuit, which comprises a direct current power supply, three auxiliary resonance circuits, a three-phase inverter and a three-phase load which are connected in sequence, each auxiliary resonance circuit comprises a resonance inductor, the three-phase inverter comprises three bridge arms, and the three bridge arms are connected with the three auxiliary resonance circuits. Each bridge arm comprises two main switches and two resonant capacitors, one main switch is connected with oneresonant capacitor in parallel, the resonant inductors on the three auxiliary resonant circuits are connected with the output ends of the three bridge arms respectively, when the main switch needs tobe switched, the resonant inductors and/or the resonant capacitors on the same phase with the main switch generate resonance, and the resonant capacitors are connected with the three auxiliary resonant circuits in parallel.
