PROBLEM TO BE SOLVED: To provide a power supply adapter capable of realizing protection against overvoltage and/or overcurrent to a battery when normal charge or boost charge is performed to the battery in electronic equipment.SOLUTION: A main control module determines whether or not output current of a power supply adapter 100 is larger than a current threshold on the basis of a current detection signal, determines whether or not output voltage of the power supply adapter is larger than a voltage threshold on the basis of a voltage detection signal, and turns off the output of DC current of the power supply adapter if the output current is larger than the current threshold, and/or the output voltage is larger than the voltage threshold. In addition, in a process that the main control module performs data communication with electronic equipment, if it is determined that the output current is larger than the current threshold, and/or the output voltage is larger than the voltage threshold by the electronic equipment, a charge off instruction is fed back to the main control module, and the main control module turns off the output of the DC current of the power supply adapter.SELECTED DRAWING: Figure 1 【課題】電子機器における電池に対して通常の充電或いは急速充電を行う時、電池に対する過電圧、及び/又は過電流の保護を実現できる電源アダプターを提供する。【解決手段】主制御モジュールは、電流検出信号に基づいて、電源アダプター１００の出力電流が電流閾値より大きいか否かを判断し、電圧検出信号に基づいて、電源アダプターの出力電圧が電圧閾値より大きいか否かを判断して、若し出力電流が電流閾値より大きい、及び/又は出力電圧が電圧閾値より大きいと、電源アダプターの直流電流の出力をオフする。また、主制御モジュールと電子機器とがデータ通信を行う過程において、若し電子機器により、出力電流が電流閾値より大きい、及び/又は出力電圧が電圧閾値より大きいと判定されると、充電オフ命令を主制御モジュールにフィードバックし、主制御モジュールは、電源アダプターの直流電流の出力をオフする。【選択図】図１
