Abstract

In this paper, an isolated bi-directional ac/dc converter with a single power conversion stage is proposed for both charging and Vehicle-to-Grid (V2G) applications of PHEV. The converter consists of two active bridges connected through a series resonant tank and a high-frequency transformer. Steady-state analysis is presented for the proposed phase-shift modulation technique between active bridges, to control the bi-directional power flow in the converter. Simulation results are presented to augment the analysis. The proposed converter has the advantages of minimal power conversion stages, high switching frequency operation and low switching losses.
