Abstract
A power converter includes a converter, a transformer, a rectifying element, a detector, and a controller. The converter converts a DC voltage into an AC voltage, the DC voltage supplied from a DC power supply. The transformer steps up or down the AC voltage. The rectifying element is a transistor, and rectifies the AC voltage that is stepped up or down by the transformer. The detector detects a transformer voltage between the transformer and the rectifying element. The controller turns off the rectifying element that is in an on-state, based on the transformer voltage.
Claims19
A power converter comprising:
- a converter configured to convert a DC voltage into an AC voltage, the DC voltage supplied from a DC power supply;
- a transformer configured to step up or down the AC voltage;
- a rectifying element being a transistor, the rectifying element configured to rectify the AC voltage that is stepped up or down by the transformer;
- a detector configured to detect a transformer voltage between the transformer and the rectifying element;
- and
- a controller configured to turn off the rectifying element in an on-state, based on the transformer voltage.
