Rectified AC Input Connected Fully Directional Universal Converter with LC Series Soft-Switching Circuit for EV; HEV & PHEV Applications

Neenu C Robin | Joju Mohan

Abstract: This paper focuses on the study of rectified ac input connected fully directional universal converter with LC series soft-switching circuit for electric vehicles (EV) ; hybrid electric vehicles (HEV) and plug-in hybrid electric vehicles (PHEV). In the applications mentioned above; the proposed converter interfaces the energy storage device with motor drive. In this paper battery is used as energy storage device. Charging and discharging action of battery; during acceleration and regenerative braking of motor take place through this bidirectional dc to dc converter. That is bucking and boosting action will take place in one direction with no inverted output voltage. Rectified ac input voltage is used here for Vdc to Vbattery bucking and boosting action. LC series resonant circuit is added with proposed bidirectional dc to dc converter for soft-switching action and closed loop PI controller is used for controlling purpose. Four modes of operation of proposed converter is described and simulations work are done in MATLAB simulink.
