| description | PROBLEM TO BE SOLVED: To provide a power-supply device with variable circuit loop impedance that allows reducing an inrush current and energy wastage of the power-supply device.SOLUTION: In a power-supply device with variable circuit loop impedance of the present invention, when a power conversion unit is in a working mode, the power conversion unit converts an AC power from an AC power supply apparatus into a DC power, and then sends a power starting signal to a first switch control unit. After the first switch control unit receives the power starting signal, the first switch control unit turns on a first switch unit, so that an overall capacitor impedance formed by a first capacitor and a second capacitor is smaller than a first capacitor impedance formed by the first capacitor. When the power conversion unit is not in the working mode, the first switch control unit turns off the first switch unit, so that the overall capacitor impedance is equal to the first capacitor impedance.
【課題】電源供給装置の突入電流およびエネルギー浪費を低減する可能な可変の回路ループインピーダンスを有する電源供給装置を提供する。【解決手段】本発明の可変の回路ループインピーダンスを有する電源供給装置は、電力変換ユニットが動作モードである場合、電力変換ユニットは、交流電源供給装置からの交流電源を直流電源に変換し、電源起動信号を第１スイッチ制御ユニットに送信する。第１スイッチ制御ユニットは、電源起動信号を受信した後、第１コンデンサおよび第２コンデンサよりなるコンデンサ全体のインピーダンスが第１コンデンサの第１コンデンサインピーダンスよりも小さくなるように、第１スイッチユニットをオンにする。電力変換ユニットが動作モード以外である場合、第１スイッチ制御ユニットは、コンデンサ全体のインピーダンスが第１コンデンサインピーダンスに等しくなるように、第１スイッチユニットをオンにしない。【選択図】図１ |
