Abstract :
This paper proposes a controller to compensate the DC-link voltage unbalance in the BLDC motor drive system based on the four-switch and half-bridge boost converter. In this paper, we can see that the proposed feedforward controller is useful for control of the neutral point voltage unbalance. The comparative experimental results show that the system became more robust by the feed-forward control of the neutral point voltage.
