A Novel Hybrid Energy Based Bidirectional Converter Using Space Vector PWM Control Strategy

Abstract

This paper proposes a Novel Hybrid Energy based bidirectional dc–dc power converter using space vector pwm to interface more than two dc sources of different voltage levels. This finds applications in hybrid electric/fuel cell vehicles (FCVs), where different dc sources of unequal voltage levels need to be connected with bidirectional power flow capability. The converter can be used to operate in both the buck and boost modes using SVPWM with bidirectional effective power control. It is also possible to independently control power flow between any two sources when more than two sources are actively transferring power in either direction.
