Abstract
A bidirectional isolated resonant converter includes a first side circuit, a second side circuit, and a resonant tank circuit. The resonant tank circuit includes a first resonant capacitor, a resonant inductor, an isolated transformer and a second capacitor. The first resonant capacitor, the resonant inductor and a first side winding of the isolated transformer are connected in series. A second side winding of the isolated transformer and the second capacitor are connected in series. The resonant inductor and the isolated transformer are integrated into an integrated magnetic component, wherein a magnetic core of the integrated magnetic component includes an inductor magnetic core portion on which an inductor winding is wound, a transformer magnetic core portion on which the first side winding and the second side winding are wound, and a common magnetic core portion shared by the resonant inductor and the isolated transformer to form closed magnetic paths, respectively.
