摘要： A DC--DC converter unit includes a power conversion transformer, a switching device for switching a DC voltage supplied to a primary winding of the power conversion transformer, a rectifying circuit for synchronously rectifying a AC voltage generated on a secondary winding of the power conversion transformer so that a DC voltage is obtained, and a reset circuit for resetting excitation energy which has been stored in the power conversion transformer by an on-operation of the switching device, so that the voltage which is switched has a square waveform.
