Implication

Simulation study demonstrates reduced switching losses in electric vehicle energy storage systems, highlighting improved efficiency in bidirectional power flow.

Key Points

To design and evaluate a novel zero-voltage transition bi-directional DC-DC converter that lowers switching losses and electrical stresses in electric vehicle energy storage systems.
Incorporated an auxiliary circuit comprising active and passive components into a conventional non-isolated bi-directional DC-DC converter to enable soft-switching.
Modeled and evaluated bidirectional operational principles in both boost and buck modes using MATLAB simulation software.
Achieved zero-voltage transition during the turn-on commutation of the main IGBT switches in both forward and reverse power flows.
Demonstrated qualitatively lower IGBT current stresses and reduced switching losses relative to conventional hard-switched designs, confirming theoretical models.
