**6. Conclusions**

In order to reduce distortion in the system, the modified PWM technique is employed along with EMI chokes. Various PWM strategies are analyzed to reduce the CMV and CMC, and a modified PWM approach is presented for a three-phase three-level inverter. The modified third harmonic injection method reduced the CMC by 60% in the system with a tradeo ff to CMV. Simulation and experimental results are provided which show good agreemen<sup>t</sup> with each other and validate that the control strategies with di fferent PWM techniques are valuable, optimize the output parameters, and are effective in preventing common mode undesirable e ffects along with and without filters. Hence, it is economic to use modified techniques so that the filter size can be reduced and the final product will be lightweight with a reduced cost compared with conventional strategies and existing PWM techniques.
