Abstract In order to improve the inverter DC bus voltage utilization rate. Improve the dynamic response of the motor speed and expand stable operation area. This paper uses a superposition principle based on the modulation control strategy, this algorithm base wave output voltage amplitude and modulation coefficient in a linear relationship, realize from linear modulation area to six pat wave smooth transition between. Based on the ground-clamp diode in three level test experimental platform, the experimental results verify the feasibility and effectiveness of the algorithm.
