A power supply includes power modules. Each of the power modules includes an input stage and an output stage. The input stage generates an intermediate voltage, and the output stage outputs a DC supply voltage according to the intermediate voltage. The input stages are controlled with at least one first common control signal having a common duty cycle, and the output stages are controlled with at least one second common control signal having a common duty cycle.
