| Abstract: | To solve the problem of over modulation, this paper proposes a improved technique based on the principle of three level inverter space voltage vector pulse width modulation and derives the corresponding time algorithm of three level inverter space voltage vector in the over modulation sectors. Simulation experimental results show that the method can restrain the content of harmonious and increase voltage utilization. |
| Keywords: | three level voltage inverter space voltage vector PWM over modulation |
