A control unit controls the amplitude of at least either an output voltage or an output current by shifting at least either a first on time or a second on time.

Power conversion apparatus including a transformer, an invertor circuit and a plurality of switching devices controlled by a controller

A power conversion apparatus includes an inductor inserted between a secondary winding and a switching device, and an auxiliary switching device inserted between the secondary winding and the switching device in parallel to the inductor. The auxiliary switching device is in an off state in a power supply mode in which an output voltage and an output current of a connector have the same polarity. The auxiliary switching device is in an on state in a power regeneration mode in which the output voltage and the output current of the connector have different polarities.

Power conversion apparatus having a switching circuit unit that includes a switching device and an auxiliary switching device

A power conversion apparatus according to one aspect of the present disclosure comprises a bridge circuit including a first switch and a second switch, a first auxiliary switch, a first auxiliary inductor, a control device, a transformer, a secondary-side inductor, a rectifier circuit, a smoothing circuit, and an output detection circuit. The control device performs an on/off operation on the first auxiliary switch if a value detected by the output detection circuit is smaller than or equal to a setting value, and maintains the first auxiliary switch in an off state if the detected value exceeds the setting value.

Power conversion apparatus

An electric power converter includes a bridge circuit, a transformer, a rectifier circuit, and a smoothing circuit. The rectifier circuit includes a first secondary-side diode disposed in a first current path extending between one end of a secondary winding and a first terminal of the smoothing circuit, a second secondary-side diode disposed in a second current path extending between the other end of the secondary winding and the first terminal of the smoothing circuit, a third secondary-side diode, a fourth secondary-side diode, a first secondary-side switching element, and a second secondary-side switching element. The first secondary-side switching element and the second secondary-side switching element are connected in common to a first node at which the first current path and the second current path are connected to each other.
