摘　　要：提出在无刷直流电动机的驱动三相逆变桥的输入端加前级降压-升压(Buck-Boost)变换器,采用转速和直流母线电流的多环反馈控制方法实现电机的控制。该方法减少了开关损耗,逆变器尺寸和成本。通过MATLAB/Simulink仿真验证了该方法的有效性和可行性。An improved topology of brushless DC motor drive with a Buck-Boost converter before 3 phase inverter,The motor can be controlled by technique-multi-loop. This method can reduce switching losses, the inverter size and cost. Effectiveness and feasibility of the proposed control method was verified by MATLAB/Simulink.
