Abstract
A bidirectional voltage conversion device includes a first half-bridge switching circuit, a transformer, a first resonant capacitor, a double-pole double-throw relay, a second half-bridge switching circuit, a resonant inductor and a second resonant capacitor. The first half-bridge switching circuit is coupled to a high-voltage power storage device. The first resonant capacitor is coupled to the first half-bridge switching circuit and a primary winding. The double-pole double-throw relay is coupled to a first secondary side winding, a second secondary side winding and a grounding terminal. The second half-bridge switching circuit is coupled to a low-voltage power storage device. The resonant inductor and the second resonant capacitor are coupled in series between the second half-bridge switching circuit and a node between the first secondary side winding and the second secondary side winding.
