A power supply includes a first circuit, a second circuit, a feedback circuit and a controller. The first circuit has a first switch, and the second circuit has a second switch. The first circuit transforms an input voltage to a middle voltage, and the second circuit transforms the middle voltage to an output voltage. The feedback circuit electrically connects to the controller and the output voltage respectively. The controller includes a first sub-control unit and a second sub-control unit. The first sub-control unit electrically connects to the first switch and the second sub-control unit electrically connects to the second switch. The controller generates a compensation voltage signal for the first sub-control unit and the second sub-control unit to control the first switch and the second switch.
