An integrated permanent magnet (PM) brushless motor driver with commutation current ripple reduction strategy is proposed in this study. The speed control and commutation current ripple reduction can both be achieved by only adjusting the duty ratio of the main switch. The other six active switches controlled by low-frequency commutation signals determined from the Hall effect sensors. The operation principles of the driver in normal conduction period and commutation period are both analyzed. To reduce the commutation ripple current, a compensation strategy is also provided by modifying the main switch duty ratio. A 500W prototype of proposed driver for a PM brushless motor with a rated speed of 3000rpm was constructed to verify the performance and validity. From the experimental results under different load and speed conditions, it can be seen that the current ripple in the commutation period can be greatly reduced up to about 50%.
