Abstract
A power module includes N inverter units outputting N AC voltages and being coupled to N high-frequency AC terminals, wherein the N high-frequency AC terminals are cascaded and connected to a post-stage rectifier circuit. A phase-shift control method for the power module includes: setting at least two phase-shift sequences, wherein phase sequence numbers of the N AC voltages of the N inverter units are different in the at least two phase-shift sequences; in one switching period, controlling the N AC voltages of the N inverter units to shift a first angle according to a first phase-shift sequence of the at least two phase-shift sequences; and in another switching period, controlling the N AC voltages of the N inverter units to shift the first angle according to a second phase-shift sequence of the at least two phase-shift sequences.
