Abstract-A five leg inverter (FLI) control is incorporated to drive two independent rated permanent magnet synchronous motors (PMSMs) for automotive applications. Also in these cases one leg of inverter is common to both the motors. The expanded two arm modulation (ETAM) has been engaged in FLI. This makes the FLI drives to use the dc link in efficient way, which is due to the fact that conventional ETAM works with voltage reference. This paper modifies the ETAM in an ingenious way to improve voltage utilization factor(VUF) further through current reference (HCC). In addition, the developed current reference expanded two arm modulation minimizes the current harmonics and torque ripple as well. The simulations are conducted in MATLAB-Simulink software. Based on the simulation results, a practical system is designed and implemented that is explained in the paper.
