The electric vehicles (EVs) operated from induction motor need clean, harmonic free AC supply for efficient operation, also the fault tolerant operation of inverter gives additional reliability to EV system. This paper presents a fault tolerant multilevel inverter for EV application. The harmonic profile of output voltage generated by fault tolerant T-type cross-connected source (TTCCS) inverter depends upon the value of gain for nearest level control (NLC) technique and modulation index for phase opposition disposition sinusoidal pulse width modulation (PODSPWM) technique. This paper presents the application of particle swarm optimization (PSO) algorithm to select the optimal gain for NLC technique and modulation index for PODSPWM technique to operate the nine-level (9L) symmetric fault tolerant TTCCS inverter with better harmonic profile. The presented simulation work is carried out in R2017b version of MATLAB. With the application of PSO, optimal value of gain and modulation index is calculated.
