Abstract
A power supply test device includes a function generator, a loading circuit, a current detection circuit, and a controller. The function generator outputs a square-wave signal to the loading circuit. The loading circuit is electronically connected to a power supply, the loading circuit regulates an output current of the power supply according to the square-wave signal. The current detection circuit cooperates with the controller in detecting a slope of the output current. The controller compares the detected slope with a preset value, and regulates the square-wave signal according to the comparison to regulate the slope of the output current.
