Performance Analysis of WBG Inverter Fed Electric Traction Drive System for EV Application

This research aims to analysis of WBG based inverter fed PMSM motor based on Zero d-axis (ZDAC) vector control method to control speed of interior permanent magnet synchronous motors (IPMSMs) for electric vehicle application. Considering machine's dynamic model and determine certain set of voltage references and angle to imitate speed of driving cycle. PMSM torque is consists of field torque and reluctant torque. By controlling q-axis and d-axis stator current controls both torque. By controlling ZDAC vector control of PMSM motor determine loss of inverter module with the help of co-simulation of MATLAB simulink and PLECS. Drive cycle and dynamics of vehicle present in MATLAB Simulink which gives reference signals to closed loop control of PMSM motor who presents in PLECS for inverter loss analysis. Inverter modules builds of Si, Sic MOSFETs for evaluation of loss analysis in this research article. From the analysis results WBG based inverter module has less power loss comparative to Si inverter module which is improving efficiency, fast operation of system. It contributes for higher power density of system as requirements of heat sink reduces. The dynamic performance of PMSM motor evaluates torque, power, stator current by taking an example of Kolkata drive cycle in MATLAB simulink.
