The present invention discloses a bidirectional power conversion DC-DC converter capable of bidirectional power reception having a high efficiency characteristic in a wide input voltage control range. The bidirectional power conversion DC-DC converter of the present invention comprises; a primary side terminal which includes primary side first and second resonance converter units and forms a path of a current flowing through a first wiring terminal of a first resonance transformer of the primary side first resonance converter unit, a primary side first resonance capacitor, a first wiring terminal of a second resonance transformer of the primary side second resonance converter unit, and a primary side second resonance capacitor in the forward operation and forms a current path which detours the primary side first and second resonance capacitors in the reverse direction operation; and a secondary side terminal which includes secondary side first and second resonance converter units which are paratactically connected to a second direct current power. The secondary side terminal forms a path of a current flowing through a second wiring terminal of a first resonance transformer of the secondary side first resonance converter unit, a second wiring terminal of a second resonance transformer of the secondary side second resonance converter unit, and a secondary side resonance capacitor which connects the second wiring terminal of the first resonance transformer and the second wiring terminal of the second resonance transformer in series in the reverse direction operation. The secondary side terminal forms a current path which detours the secondary side resonance capacitor in the forward operation. |
