This paper proposes battery based Interleaved boost converter (IBC), along with multilevel inverter(5-level) feeding the Permanent Magnet Synchronous Machine (PMSM)motor to drive the wheels of the electric vehicle system. From past few decades automobile engineering and power electronics engineering combinedly working to introduce high speed, efficient charging vehicle by overcoming the issues of environment caused by fuel drives. The heart of this system is dc-dc (IBC)converter, which increases dc voltage of battery to high level. The dc voltage converted to ac through inverter. The inverter modifies the dc source of IBC to ac through Pulse width modulation (PWM)technique, by using MOSFET switches in inverter. Finally, ac energy feeds the (PMSM)drive. The existing topology converter used one switch and single inductor with 0.5 duty ratio, whereas proposed topology fed with two switches and two inductors connected in parallel, which reduces the current ripples and size of inductor, there by circuit size also reduced. Here the duty ratio is maintained >0.5, which increases the voltage level of battery pack and maintains maximum power at output side. The results of the proposed circuit are verified through Digital simulation studies are carried out using MATLAB(R2017b)/Simulink software.
