Abstract
A magnetic balance circuit of a bidirectional resonant converter and a control method thereof are provided. The magnetic balance circuit includes a primary conversion circuit, a transformer, a secondary conversion circuit, and a controller. Said primary conversion circuit is connected to a primary winding of said transformer through a first capacitor, a current transformer is set between the secondary winding of said transformer and said secondary conversion circuit. According to the positive component of the current in the cavity of the secondary conversion circuit and the negative component of the current in the cavity of the secondary conversion circuit, said controller further controls the duty ratios of the switches in the secondary conversion circuit. In the invention, the magnetic deviation phenomenon on both sides of the bidirectional resonant converter is effectively eliminated to achieve balance control for the magnetic circuit, thereby avoiding saturation.
