Circulating current reduction in parallel IBC of AWD EV.

The grid current ripple in Integrated Battery Charger of All Wheel Drive Electric Vehicle is higher.

Application of interleaving to Parallel IBC of AWD EV reduces grid current ripple, but causes the circulating current to ow between the inverters.

Currently working on the modulation techniques to reduce the ow of the circulating current. Seminar Project

Circulating current reduction in parallel grid connected two level VSI.

Interleaved PWM applied to parallel system creates circulating current ow between the inverters.

Carrier based modulation technique was proposed to reduce the circulating current and is veri ed through simulation in Matlab-Simulink.

Submitted a manuscript in IEEE PEDES-2020 conference. Course/Lab Projects
