Abstract: Disclosed is a control method for a hybrid parallel integrated power supply. Under the condition of a 2:1 current ratio between a Si-based inverter and a SiC-based inverter, an optimal power ratio between the two inverters is obtained by reducing a power loss of a fundamental wave component on the Si-based inverter. Based on the fitting for effective values of a harmonic current on the Si-based inverter, an optimal switching frequency of the Si-based inverter and a relationship between a minimum harmonic-current conduction loss and a switching loss under the optimal switching frequency are obtained. Zero sequence components of the current are eliminated through rapid switching of the SiC-based inverter, to suppress harmonic waves.
