Newly-constructed bidirectional DC/DC converter topology with high voltage conversion ratio for vehicle to DC-microgrid (V2DCG) system
The objective of this paper is to present a novel bidirectional dc/dc converter topology with a high voltage conversion ratio for electric vehicle (EV) batteries connected to dc-microgrid system. In this study, an unregulated level converter (ULC) cascaded with a two-phase interleaved buck-boost charge-pump converter is introduced to achieve a high conversion ratio with very simple control circuits. In discharge mode, the topology acts as a two-stage voltage-doubler boost converter to achieve high step-up conversion ratio (48V to 400V). In charge mode, the converter acts as two cascaded voltage-divider buck converters to achieve high voltage step-down conversion ratio (400V to 48V). The steady-state analysis and numerical simulation are made to verify the performance of the proposed newly constructed bidirectional converter.
