A modified state-plane control of a bi-directional Series Resonant Converter for an EDLC Energy Storage System in Hybrid Electric Vehicles

The state-plane control consists on making use of the state-plane to monitor the resonant tank variables in the Series Resonant Converter (SRC). Based on this technique, this article will propose and analyze a novel control strategy that is able to step up and down the voltage in a SRC. Both analytical and simulation results are provided with and without a high frequency transformer.
