POWER CONVERTER HAVING EMI FILTER COMMON TO MULTIPLE CONVERTERS

摘要

A power supply system is disclosed that includes a first interleaved power supply, a second interleaved power supply, and a common electromagnetic interference filter. The common electromagnetic interference filter is configured to provide DC power from a DC power source to both the first interleaved power supply and the second interleaved power supply. In one example, the common electromagnetic interference filter comprises a localized filter stage configured to receive DC power from the DC power source, and a distributed filter stage configured to receive DC power from the localized filter stage. The distributed filter stage includes a first set of common mode capacitors electrically connected to and physically proximate input power lines of the first interleaved power supply, and a second set of common mode capacitors electrically connected to and physically proximate input power lines of the second interleaved power supply.
