abstract

• Common mode voltage is an important issue in motor drive systems since its dynamics could produce leakage ground current reducing the machine lifetime. In order to contribute to reduce the effects of the leakage ground current, three-phase power inverters can be designed using dedicated pulse width modulation strategies. Space vector modulation technique is a commonly used continuous method due to its flexibility to implement different vector sequences. In this paper it is proposed a space vector based modulation technique to reduce common mode voltage in a three-phase ANPC inverter. An analysis and comparison regarding conventional space vector modulation techniques are performed. Numerical results are obtained to prove the feasibility of the proposed method. © 2020 IEEE.
