摘要： A power supply controlling apparatus includes a first power supply unit that supplies DC power to a load using power supplied from a commercial power supply, a power detecting unit that detects an input voltage and an input current input from the commercial power supply to the first power supply unit, and a control unit that controls the input current to be a constant current having an upper limit current value in response to the input voltage by controlling DC power supplied to the load from the first power supply unit based on the input voltage and the input current which are detected by the power detecting unit.

摘要： A power conversion device includes a power conversion circuit, a memory, a voltage detection circuit, a current detection circuit, and a control circuit. The power conversion circuit controls a switching device based on a switching pulse signal to convert direct current power into alternating current power and output the alternating current power to a power supply target. The memory stores an alternating current phase difference. The voltage detection circuit detects an alternating current voltage effective value. The current detection circuit detects an alternating current effective value. Based on the alternating current phase difference, the alternating current voltage effective value, and the alternating current effective value, the control circuit stops output of the switching pulse signal at a time when an alternating current has a value of 0.
