Abstract

A method for controlling a three-phase resonant circuit and related apparatuses are provided, relating to the technical field of circuit control. The method includes: obtaining a target error value, where the target error value is a difference between a reference value of a predetermined electrical parameter of the three-phase resonant circuit and a sampled value of the predetermined electrical parameter of the three-phase resonant circuit; adjusting, in responding to the target error value being greater than or less than 0, an operation parameter of the three-phase resonant circuit to cause the target error value to be 0; and switching, in responding to the target error value being greater than or less than 0, an operation mode of the three-phase resonant circuit from a current mode to a target mode after the operation parameter has been adjusted to a preset value, where the target mode includes a three-phase continuous mode, a three-phase hiccup mode, a two-phase hiccup mode or a two-phase variable duty cycle mode.
