摘要： A three-phase rectification circuit rectifies output voltage of a three-phase AC power supply, a step-up converter circuit steps up the output voltage, and a smoothing device smoothes the stepped-up output voltage. A voltage detection circuit detects output voltage VoL of the smoothing device, and an AC current component detection circuit extracts AC component included in output current of the three-phase rectification circuit and outputs a detection signal ViL corresponding to the AC component. A control circuit calculates a deviation ΔVdc1 (=Vs−VoL−ViL) among an output voltage instruction Vs for output voltage of the step-up converter circuit and detection signals VoL and ViL obtained by the detection circuits, and generates a pulse signal for suppressing the deviation ΔVdc1 to zero, thereby performing PWM control for a switching device of the step-up converter circuit.

摘要： The present invention provides a power device including a converter part (2) for converting an AC voltage to a DC voltage; an inverter part (3) for converting the DC voltage outputted from the converter part (2) to the AC voltage; and a transformer (4) having an inductance forming a series resonance circuit together with an electrostatic capacity of a load (20) to boost the AC voltage outputted from the inverter part (3). In the power device, an inductance (7) is connected to the output part of the inverter part (3) in parallel with the transformer (4). Thus, in a discharge part 6 provided in the load (20), since when a discharge is not generated, a recovery current is not supplied to a circulating current diode in the inverter part (3), or the quantity of the recovery current is reduced, the heat generation of the circulating current diode can be suppressed without increasing the number of elements of the circulating current diode.
