Abstract :
In a variable frequency and adjusting speed system with high power, the balance of neutral point is very important. This paper brings out a set of complete neutral point control strategies based on the improved space vector pulse width modulation (SVPWM) control strategy, and has obtained comparative perfect effects in practice.
