摘要
High-power-density bidirectional dc-dc converters consisting of buck-and-boost converters are extensively used in Electric Vehicles (EV)/Hybrid Electric Vehicles (HEV) due to their smaller size and low cost. But conventional bidirectional dc-dc converter has a right half plane (RHP) zero in the open loop control to output voltage transfer function in boost mode of operation. Due to this RHP zero controller design is not simple for boost operation. A modified non-isolated minimum phase bidirectional DC-DC converter is presented in this paper. The bidirectional DC-DC converter displays the minimum phase behavior due to the complete exclusion of the RHP zero. Due to the minimum phase behavior, the bidirectional DC-DC converter gives excellent dynamic performance under heavy load requirements. Simulation and experimental results are presented to verify the modified non-isolated minimum phase bidirectional DC-DC converter.
