Abstract :
Two space vector control schemes are presented to improve current and neutral point voltage performance for a boost type three-level rectifier. While the exact vector scheme can make the AC line current follow the command current better, the average vector scheme can balance the DC neutral point voltage better. Both methods show much improved line current and neutral point voltage performance. Limitations and trade-offs of each scheme are also discussed in the paper. Simulation results are obtained with the proposed schemes
