    • A high-efficiency power supply apparatus is provided in light of the reduction of the switching loss. The power supply apparatus connected between the AC power supply and the DC load converts the AC power supplied from the AC power supply to the DC power and supplies it to the DC load. The power supply apparatus comprises the first switching circuit for outputting the switched positive and negative voltages to the primary winding of the transformer, a second switching circuit for supplying the DC power induced in the secondary winding of the transformer and switched to the DC load connected to the second AC terminals, a resonance inductor serial-connected to the primary winding, and a control unit for controlling the switching operations performed by the first and second switching circuits. The control unit substantially short-circuits the second AC terminals by controlling the switching operations performed by the second switching circuit.
    • 鉴于开关损耗的降低,提供了高效率的电源装置。 连接在AC电源和DC负载之间的电源装置将从AC电源提供的AC电力转换为DC电力并将其提供给DC负载。 电源装置包括:第一开关电路,用于将开关正电压和负电压输出到变压器的初级绕组;第二开关电路,用于提供在变压器的次级绕组中感应的直流电力,并切换到连接到 第二AC端子,串联连接到初级绕组的谐振电感器,以及用于控制由第一和第二开关电路执行的开关操作的控制单元。 控制单元通过控制由第二开关电路执行的开关操作来使第二AC端子短路。

    • Disclosed is a small-size, high-efficiency, isolated, bidirectional DC-DC converter. The bidirectional DC-DC converter includes a transformer in which windings are magnetically coupled, switching circuits, a diode which is connected in parallel with a switch, smoothing capacitors, and a control section. First and second DC power supplies, which are connected in parallel with the smoothing capacitors, respectively, provide bidirectional electrical power transfer. When electrical power is to be transferred from the first DC power supply to the second DC power supply, the switch is maintained in the ON state. When, on the other hand, electrical power is to be transferred from the second DC power supply to the first DC power supply, the switch is maintained in the OFF state to prevent a reverse electrical power flow from the first DC power supply.
