Abstract
A bidirectional DC-DC converter is configured with a transformer that has a first winding and a second winding, a first DC-AC converter that is provided between a first DC voltage line and the first winding, a second DC-AC converter that is provided between a second DC voltage line and the second winding, and a controller that performs a switching control operation that bidirectionally transmits DC power between the first DC voltage line and the second DC voltage line. When the bidirectional DC-DC converter is in a light load operation state, the controller provides an operation stop period that periodically stops the switching control operation so as to perform an intermittent switching control operation.
