Abstract
A control method includes determining an error value of a reverse input current of a phase-shifted full-bridge circuit based on sampling and reference values of the reverse input current, determining a compensation control quantity of a switch drive signal of the phase-shifted full-bridge circuit based on the error value. The compensation control quantity corresponds to a period or a duty cycle of the switch drive signal. The method further includes determining period and duty cycle control quantities of the switch drive signal based on the compensation control quantity. The period control quantity is within a value range of the period of the switch drive signal, and the duty cycle control quantity is within a value range of the duty cycle of the switch drive signal. The method also includes controlling the switch drive signal based on the period control quantity and the duty cycle control quantity.
