Abstract This paper analyzed half bridge pulse width modulation and whole bridge pulse width modulation of brushless DC motor respectively based on regenerative braking principle. Combined with whole bridge modulation and half bridge modulation, a novel hybrid regenerative braking control method was proposed to solve the problems of freewheeling in the inactive phase and critical speed. Whole bridge modulation was used above the critical speed to avoid the freewheeling and eliminate the torque ripple. While half bridge modulation was adopted below the critical speed, so the power losses reduced and the efficiency of the drive system improved. Experimental results prove that the new method in braking control can not only improve the efficiency of energy feedback but also smooth the braking process.

Key words： Brushless DC motor half bridge modulation whole bridge modulation regenerative braking
