Abstract: A power supply apparatus and a control method thereof are provided. Power conversion is performed according to a switching signal group to provide an output voltage and an output current. An error value between the output voltage and a reference voltage is multiplied by a proportional parameter to obtain a proportional result. The error value is multiplied by an integration parameter to obtain a first calculation value which is then accumulated over time to obtain an integration result. When a slope of the output current is greater than a reference slope and a slope of the output voltage is negative, the slope of the output voltage is multiplied by a differential parameter to obtain a second calculation value which is then added to the integration result over time. A duty cycle of the switching signal group is adjusted according to the sum of the proportional result and the integration result.
