POWER SUPPLY DEVICE HAVING AC POWER DETECTION CIRCUIT

To provide a power supply device having an AC power detection circuit.SOLUTION: A power supply device having an AC power detection circuit includes a main power-supply processing circuit, and an AC power detection circuit electrically connected to the main power-supply processing circuit. The AC power detection circuit includes a rectification unit electrically connected to the main power-supply processing circuit, and a frequency processing unit electrically connected to the main power-supply processing circuit and the rectification unit. The rectification unit rectifies AC power to obtain rectified power. When the frequency of the rectified power is higher than a predetermined frequency, the frequency processing unit notifies the main power-supply processing circuit, and the main power-supply processing circuit rectifies the AC power to obtain an output DC power.SELECTED DRAWING: Figure 1 【課題】交流電力検出回路を有する電力供給装置の提供。【解決手段】本発明に係る交流電力検出回路を有する電力供給装置は、主電源処理回路と、主電源処理回路に電気的接続されている交流電力検出回路とを含む。交流電力検出回路は、主電源処理回路に電気的に接続されている整流ユニットと、主電源処理回路及び整流ユニットに電気的に接続されている周波数処理ユニットとを含む。整流ユニットは、交流電力を整流して整流電力を得る。整流電力の周波数が所定の周波数よりも高い場合、周波数処理ユニットは主電源処理回路に通知して、主電源処理回路が交流電力を整流して出力直流電力を得る。【選択図】図１
