摘　　要：深入分析研究了三相全桥逆变电路控制的无刷直流电机(BLDCM)在半桥调制方式下由电动状态转入回馈制动的过程,并对BLDCM的电动与回馈制动控制系统做了仿真和实验。实验结果表明,采用三相全桥逆变电路控制的BLDCM在半桥调制方式下可以很好地实现从电动状态到回馈制动状态的过渡。该控制方法硬件电路简单、控制简便,具有一定的推广和应用价值。This paper studies on the process of the working state of the （BLDCM） which turns drive state to the regenerative break state.This control system bases on three phase full bridge and uses the half bridge modulation control method. The experiments show that the control method control BLDCM working from the drive state to the regenerative brake state well.The hardware of this system is not complex and controlled easily,so the control system can be used widely.
