  • POWER SUPPLY WITH RIPPLE ATTENUATOR
    Publication number: 20070236968
    Abstract: A power supply configured for converting an input AC voltage into an output DC voltage having a desired voltage level is provided. The power supply includes a front-end power converter such as a PFC converter which is configured to convert the input AC voltage into an intermediate DC voltage generated across an output capacitive unit, and a back-end power converter such as a DC-DC converter which is configured to convert the intermediate DC voltage into an output DC voltage having a desired voltage level. The power supply further includes a resonant network consisted of a filter which is made up of at least one inductive filtering element having an inductive impedance and a capacitive filtering element having a capacitive impedance. The resonant network is placed between the front-end power converter and the back-end power converter, and coupled with the output capacitive unit for filtering the current flowing into the output capacitive unit.
