Bidirectional isolated resonant converter

A bidirectional isolated resonant converter, comprising a first side circuit, a second side circuit, and a resonant tank circuit electrically coupled between the first side circuit and the second side circuit,

• the resonant tank circuit comprising a first resonant capacitor, a resonant inductor, an isolated transformer and a second capacitor, wherein the first resonant capacitor, the resonant inductor and a first side winding of the isolated transformer are connected in series, and a second side winding of the isolated transformer and the second capacitor are connected in series;
• wherein the resonant inductor and the isolated transformer are integrated into an integrated magnetic component, a magnetic core of the integrated magnetic component comprising an inductor magnetic core portion on which an inductor winding of the resonant inductor is wound, a transformer magnetic core portion on which the first side winding and the second side winding of the isolated transformer are wound, and a common magnetic core portion shared by the resonant inductor and the isolated transformer to form closed magnetic path, respectively;
• wherein when the same current is flowing in the inductor winding and the first side winding, a magnetic flux generated by the resonant inductor and a magnetic flux generated by the isolated transformer have the same direction on the common magnetic core portion.
