Study on a new method to eliminate the common-mode voltage based on improved SHEPWM

Reducing the common-mode voltage of three-level active neutral point clamped (ANPC) inverter is of great significance in high-voltage and high-power applications. Using the improved specific harmonic elimination pulse width modulation (SHEPWM) combined with multi-objective particle swarm optimization to eliminate the common-mode component of output voltage of the inverter. The simulation result shows that this method is effective.
