1. An inverter circuit control method comprising:
determining a direct current DC bus voltage and an output leakage current of a target inverter circuit;
determining, according to the DC bus voltage, whether the target inverter circuit satisfies a preset modulation condition; and
adjusting, according to the DC bus voltage or the output leakage current, a modulation harmonic wave to be injected into a sinusoidal pulse width modulation (SPWM) signal in a case that the target inverter circuit satisfies the preset modulation condition, such that total harmonic distortion of a current of the target inverter circuit is within a preset range.
