Abstract
A bidirectional voltage converter that includes a transformer, a first bridge circuit, a second bridge circuit and a controller is introduced. The first bridge circuit is coupled to a first side of the transformer and a first voltage source, and the first bridge circuit comprises a first switch, a second switch, a third switch and a fourth switch. The second bridge circuit is coupled to a second side of the transformer and a second voltage source. The controller is configured to set the first bridge circuit to a half-bridge configuration by turning off the third switch, turning on the fourth switch, and alternately turning on and off the first switch and the second switch in response to determining that a voltage of the second voltage source is less than a predetermined threshold. An operation method of the bidirectional voltage converter is also introduced.
