CMV reduction in a three-to-seven phase direct matrix converter using SVPWM
Rahman K.; Al-Emadi N.; Al-Hitmi M.; Iqbal A. ( Institution of Engineering and Technology , 2019 , Article)The pulse-width modulation (PWM)-controlled modern electric drives causes some serious problems such as the generation of common-mode voltage (CMV) and high dv/dt. The CMV might cause high-frequency leakage currents that ... -
Common mode voltage reduction in a three-to-five phase matrix converter fed induction motor drive
Rahman, K.; Iqbal, Atif; Al-Emadi, Nasser; Ben-Brahim, Lazhar ( Institution of Engineering and Technology , 2017 , Article)Multiphase power converters generate common mode voltage due to switching actions of the power switches. The resulting common mode current in multiphase motor drives flow through the bearing and shaft. Continuous flow of ... -
