This paper presents comparative study of three-level (3L) inverters fed induction motor (IM) drive operated with closed loop volt per hertz (V/f) control scheme. The performance of 3L inverter topology, namely cascaded H-bridge (CHB) and neutral point clamped (NPC) is compared with two-level (2L) inverter topology for IM drive (IMD) operated with closed loop V/f control scheme for electric vehicle (EV) application. The performance of 2L inverter and 3L inverters fed IMD is analyzed with Simulink model created in R2017b version of MATLAB at variable torque and speed. Performance of all the three inverters for IMD is compared with various common parameters. It is observed that with the application of V/f control scheme, wide variation in speed is obtained for EV application along with improvement in various performance parameters of complete system.
