Abstract
A series-parallel switching circuit for bidirectional power conversion is provided. The series-parallel switching circuit includes a first bidirectional direct current (DC) voltage source and a second bidirectional DC voltage source, a first bidirectional DC/DC isolation conversion circuit and a second bidirectional DC/DC isolation conversion circuit, a series-parallel switching switch, a first output filter capacitor and a second output filter capacitor, a bleeder circuit, and a soft-start circuit. The series-parallel switching switch is configured to connect the first bidirectional DC/DC isolation conversion circuit and the second bidirectional DC/DC isolation conversion circuit in series or in parallel. When the series-parallel switching switch is switched, a voltage across the first output filter capacitor and a voltage across the second output filter capacitor are unchanged.
