Abstract

This paper proposes a new wide range bidirectional buck-boost dc-dc converter with improved voltage gain in either forward (discharging) or backward (charging) direction for electric vehicle (EV) applications. The converter has high-voltage gain ratio with no theoretical limits in the output voltage...
