Abstract

A current sharing control method and an AC-DC conversion system are provided. The method is applied to a current sharing controller configured to control an operating state of an AC-DC converter comprising at least two rectification units. Each of the at least two rectification units is in a bridge topology combined with an LLC resonant tank. The method comprises: acquiring current sampling values of the at least two rectification units; determining a target phase shift angle of each of the rectification units according to the current sampling values, wherein the target phase shift angle is used to indicate a duration of an input voltage of the LLC resonant tank being in a zero-level state; controlling, according to the target phase shift angle of each of the rectification units, a control signal of a target switch in a bridge topology of each of the rectification units to perform phase shifting.
