Beschreibung
Zusammenfassung:	A three-phase resonant dc-dc converter for a fuel-cell power conditioning system is provided to be effectively applied to the power of which lifetime or characteristic is influenced by a high-frequency ripple of an output current. A three-phase resonant dc-dc converter includes a three-phase inverter, an inductor(8), a capacitor(7), and a three-phase diode bridge. The three-phase inverter has a switching member which is connected to both terminals of a direct current side and is configured to output an alternating current. The inductor and the capacitor each are connected to a transformer having a primary low voltage wire and a secondary high voltage wire in series. The secondary high voltage wire is connected to the three-phase diode bridge to generate a high voltage direct current. A power(1) is constituted of a direct current power such as a fuel cell. The power is supplied to a driving member(3) and allows the direct current to be converted to the alternating current.
