The electric vehicle with compact inverter size using modified H-bridge inverter with modified topology has proposed. The modified topology use single DC source and with proposed SSVPWM. The SSVPWM was generated using sampled reference frame algorithm this algorithm used only sampled amplitude of reference phase voltages. This reduces computation time in DSP controllers where conventional algorithm requires more machine cycle to execute. The inverter output is fed to induction motor which propels the rear wheel. The sudden acceleration and de-acceleration will increase the switching stress and harmonics in the output. The neuro fuzzy optimization is used to mitigate the harmonics and bring down to the EN 50160 gride code. This model has been developed successfully using dsPIC with 5-level H-bridge inverter and has been tested in 2.2 kW induction motor.
