摘要： A first DC/DC converter is of a constant voltage control type and is controlled so as to keep the voltage of an electric generation bus at a predetermined target value. A second DC/DC converter is of a constant current control type and is controlled so as to keep input current or output current at predetermined target current. A control circuit determines an optimum target value of electric generation bus voltage, based on different algorithms, in accordance with all or some of modes A to C which are classified by the charging/discharging condition of a second electric storage device, and controls the first DC/DC converter so that the electric generation bus voltage becomes the determined target value.

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： 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.
