This paper presents the small signal analysis and controller design of Dual Inductor Current-Fed Bidirectional Converter For Fuel Cell Vehicle. The converter achieves zero-current switching (ZCS) of the primary-side switches and zero-voltage switching (ZVS) of the secondary-side switches. A proposed secondary-modulation clamps the voltage across the primary-side devices naturally and eliminates switch turn-off voltage spike concern with ZCS without any additional circuit. State space averaging technique is used to derive the small signal model. The controller is designed using two loop average current control. Frequency response curves using MATLAB and simulation results using PSIM 9.0 are presented to verify to verify the controller design and converter's transient performance.
