SERIES ACTIVE RIPPLE FILTER

摘要

According to one aspect, embodiments of the invention provide a power system including an input configured to be coupled to a power source and to receive input power from the power source, an output configured to be coupled to a load and to provide output power to the load, a power converter coupled between the input and the output, and an active ripple filter coupled to one of the output and the input including a DC link having at least one DC link capacitor and configured to generate a cancelling ripple voltage to cancel a ripple current associated with the power converter.
