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.

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： A DC-DC converter in which a primary side and a secondary side are insulated by a transformer, includes: two diodes having anodes respectively connected to both ends of a secondary winding of the transformer and cathodes connected to each other; a series circuit composed of a resistor and a capacitor connected in series; and a snubber circuit formed by connecting the cathodes of the diodes to the connection point between the resistor and the capacitor. Surge voltage caused on the secondary side of the transformer is clamped at the voltage of the capacitor, and surge energy stored in the capacitor is regenerated to a load via the resistor. Thus, surge voltage caused on the secondary side of the transformer is suppressed with a simple configuration, and effective use of surge energy is ensured.
