    摘要： An inverter circuit is connected in series to an AC power supply, and at the subsequent stage, a smoothing capacitor is connected via a converter circuit including semiconductor switching devices. A control circuit controls the converter circuit by providing a short-circuit period for bypassing the smoothing capacitor in each cycle, and controls the inverter circuit to improve the power factor of the AC power supply by using a current instruction such that the voltage of the smoothing capacitor becomes a target voltage. When the voltage of a DC voltage source of the inverter circuit has exceeded a predetermined upper limit, the control circuit increases the current instruction to control the inverter circuit, thereby increasing the discharge amount of the DC voltage source. Thus, even if the voltage variation of the DC voltage source of the inverter circuit increases, it is possible to stably continue the control.

    摘要翻译： 逆变器电路与AC电源串联连接，在后续阶段，通过包括半导体开关器件的转换器电路连接平滑电容器。 控制电路通过在每个周期中提供用于旁路平滑电容器的短路周期来控制转换器电路，并且通过使用电流指令来控制逆变器电路来提高交流电源的功率因数，使得平滑电压 电容器成为目标电压。 当逆变器电路的直流电压源的电压超过预定的上限时，控制电路增加用于控制逆变器电路的电流指令，从而增加直流电压源的放电量。 因此，即使逆变器电路的直流电压源的电压变化增大，也可以稳定地进行控制。

    摘要： A power conversion apparatus includes a high-power-factor converter section converting an AC voltage to a DC voltage, a smoothing capacitor, a DC/DC converter section, and a control circuit. The control circuit controls the high-power-factor converter section such that the power factor of AC is controlled and a DC voltage follows a target value, and performs duty control for semiconductor switching devices such that a DC voltage from the DC/DC converter section to a load follows an instruction value. In accordance with the DC voltage, the control circuit adjusts the DC voltage target value of the high-power-factor converter section such that the duty ratio of the semiconductor switching devices approaches a set value, thereby optimizing the duty ratio of the semiconductor switching devices and reducing power loss.
