Abstract:

The EV charging infrastructure is categorized as AC charging points called as EVSE (Electric Vehicle supply equipment) and DC charging ports called as Quick Chargers. The size of modern Li-ion batteries for EV applications is around 20-25 kWh, and hence the required power output of the quick charger is expected to be around 50 kW, so as to complete the charging in under thirty minutes. The high capacity requirement makes the quick chargers both bulky and expensive. The AC chargers available in the market deliver about 6.6kW and need the onboard chargers to rectify the charger output to a regulated DC output, to charge the battery. The specifications of the onboard chargers are constrained by the dimensions & specifications of the isolation transformer. It is therefore proposed to do away with the isolation transformer and have a suitable filtering mechanism to suppress the high frequency disturbances from reaching the sensitive equipment onboard the charger. The paper studies the effect of such a strategy on the power quality with the help of two power conversion strategies for controlling a 3×1 matrix converter. © 2017 IEEE.
