DC-DC CONVERTER
First Claim
1. A DC-DC converter, comprising:
- a first series circuit in which a resonance reactor, a primary winding of a transformer, and a switching element are connected in series, the first series circuit being connected to both ends of a direct current power supply;
a second series circuit in which a first rectifier, a current resonance capacitor, and a secondary winding of the transformer are connected in series, the second series circuit being connected to both ends of the direct current power supply;
a rectifying/smoothing circuit having a second rectifier and a smoothing capacitor and connected to both ends of a series circuit of the current resonance capacitor and the secondary winding of the transformer;
an output voltage detection circuit for detecting an output voltage of the rectifying/smoothing circuit; and
a control circuit that turns on and off the switching element based on an output voltage signal from the output voltage detection circuit.
