Abstract
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.
Claims20
A power supply comprising:
- a plurality of power modules, each of the plurality of power modules comprising:
- a first converter configured to generate an intermediate voltage;
- and
- a second converter configured to output a DC supply voltage according to the intermediate voltage;
- wherein the first converters in the plurality of power modules are configured to be commonly controlled according to an input current flowing through the plurality of power modules, and the intermediate voltages in the plurality of power modules;
- wherein the second converters in the plurality of power modules are configured to be commonly controlled according to outputs of the plurality of power modules.
