Abstract

     In this paper, the application of current source converter (CSC) for EV battery charging is explored. This allows the exploitation of the inherent Buck-Rectifier (i.e. rectifier with voltage step-down capability) characteristic of CSC, which is ideal for interfacing low voltage DC sources like EV battery with higher voltage AC grid. To increase redundancy, hence improving the system’s reliability, a dual-parallel CSC configuration is considered and compared with similar operation using just single CSC. It is found that by phase-shifting the PWM carrier for the dual-parallel CSC, the DC-link current ripple can be reduced. Using simulation results in PLECS, the effect of carrier phase shifting is explored, where minimum DC-link current ripple is found to be attainable at 180° phase shift. At the same time, the CSC was able to draw sinusoidal current from the grid without creating severe power quality issues.
