Abstract

This paper presents a feedforward ripple cancellation technique for use with a full-bridge DC-DC converter. The full-bridge is used to energize an inductive coupling that serves as an isolating connector in a battery charging system. Feedforward ripple cancellation prevents large AC currents from flowing into the battery terminals in response to unavoidable AC ripple on the inverter input bus voltage. A computationally inexpensive technique for implementing ripple cancellation using either analog or digital hardware is described and demonstrated on a 1500 watt hardware prototype
