起发一体式无刷直流电机控制器设计

Design of integrated BLDC motor controller for starting andgenerating

基于无刷直流电机的数学模型,文章分别分析了控制及发电策略,在起动过程采用三相全桥逆变电路拓扑结构及六步换相控制策略;在发电部分采用二极管整流和BUCK稳压电路串联的电路拓扑结构,将电源管理芯片UC3843作为BUCK电路控制器件,完成了系统架构设计,具有一定的参考意义。

Based on the mathematical model of BLDC motor,this article analyzes the control and power generation strategies respectively.During the starting process,a three-phase full bridge inverter circuit topology structure and a six step commutation control strategy are adopted.In the power generation section,a circuit topology structure of diode rectification and BUCK voltage stabilization circuit in series is adopted,and the power management chip UC3843 is used as the BUCK circuit control device to complete the system architecture design,which has certain reference significance.
