ABSTRACT:
An automatic voltage-identifying power supply device has a control module, a voltage regulation circuit, a current load measuring circuit electrically connected with an external post-stage power-receiving device, a power supply circuit and a pre-stage power supply device. After the post-stage power-receiving device is electrically connected with the current load measuring circuit, the control module can control the voltage regulation circuit to output a test voltage signal to the post-stage power-receiving device so that the test voltage signal is altered according to a preset sequence (e.g. progressively increasing) and the current load measuring circuit measures a response current signal of the post-stage power-receiving device corresponding to the test voltage signal. When a variation of the response current signal or a power variation is stable, the control module sets up the stable test voltage signal as an input voltage to the post-stage power-receiving device.
