NEW CARRIER PWM TECHNIQUE TO REDUCE COMMONMODE VOLTAGE IN THREE PHASE FIVE LEVEL CASCADE INVERTER

Abstract

In this paper, the new PWM algorithm for reducing the comon mode voltage
apply in the cascade 3-phase 5 level inverter is presented. This proposed
algorithm is implemented on the the representing the reference voltage vector
by the vectors that do not generate the common mode voltage. The analysis was
done to select the appropriate component vectors. Simulations and experiments
to clarify the analytical results and contribute to validate the theoretical analysis.
