Abstract

A control method for an LLC resonant converter includes: dividing an input voltage into four voltage segments: a low voltage, a medium-low voltage, a medium-high voltage, and a high voltage, and correspondingly adopting a full-bridge PFM control mode, a full-bridge PWM control mode, a half-bridge PFM control mode, and a half-bridge PWM control mode respectively. This control method is applicable to a wide input voltage range to achieve steady-state control over an LLC resonant converter, and can maintain a high efficiency of the LLC resonant converter within the whole input voltage range and can also be used in scenarios where a wide output voltage occurs.
