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: determining a target adjustment phase based on the absolute values of instantaneous values of three-phase input voltages of the at least two rectification units; determining a target duty cycle of the target adjustment phase in each of the rectification units based on the current sampling values of the at least two rectification units; and adjusting, based on the target duty cycle of the target adjustment phase in each of the rectification units, a duty cycle of a control signal for a switch in each of the rectification units.
