Abstract
A power supply system has a current source configured to provide an output current, a load supplied by the current source, and a current ripple suppression circuit. The current ripple suppression circuit has a first end and a second end, wherein the first end of the current ripple suppression circuit is coupled to the load, and the second end of the current ripple suppression circuit is coupled to a reference ground; wherein the current ripple suppression circuit is configured to suppress the current ripple in the output current and adaptively adjust the output current of the current source at a predetermined current level.
