Abstract
A battery charging system for charging a battery of an electric vehicle that is coupled to a charge probe by way of a diode bridge and a fourth element capacitor. The system includes a voltage source and a plurality of battery chargers connected in parallel across the voltage source that each includes a series tank circuit and an isolation transformer. The charge probe is coupled to the isolation transformers of the parallel plurality of battery chargers. A distributed fourth element capacitor is coupled across the isolation transformers of each of the parallel plurality of battery chargers.
