| description | A power-supply control apparatus of the present invention is configured such that a control circuit, to which detection information from an input voltage detection part, input current detection part, rectified current detection part, and output voltage detection part is inputted, outputs a driving command signal which is for performing ON/OFF operation of a switching element so that a rectified current from a rectifying circuit becomes a waveform in which a sine-wave current waveform having the same phase as an input voltage is rectified; and a breaking circuit interrupts the driving command signal to be inputted to the rectifying circuit from the control circuit when an absolute value of an input current detected by a current transformer of the input current detection part exceeds a previously determined abnormal input current threshold. |
