The invention relates to a brushless direct-current motor boost integrated driving system and a control method. A pre-stage Boost DC-DC converter topology circuit is formed through the coupling use ofswitching devices, and a voltage regulation effect on an input source is realized; meanwhile, a rear-stage three-phase full-bridge power converter topology circuit is formed, the output voltage adjusted by the front-stage Boost DC-DC converter serves as an input source of the rear-stage three-phase full-bridge power converter topology circuit to supply power to a brushless direct-current motor todrive, and the effect of motor speed regulation is achieved; the integrated topology is realized on a hardware circuit, an integrated control mode is realized on a system control method, and the integrated topology is simple in circuit, small in size, high in adaptability to input source battery voltage, suitable for being applied to the field of pure electric vehicles, capable of driving an electric vehicle to run and collecting braking energy under the condition that the electric vehicle brakes, the energy is saved, and the running distance of the electric vehicle is increased.

    本发明涉及一种无刷直流电机升压集成驱动系统及控制方法,通过对开关器件耦合使用,组成前级Boost DC‑DC变换器拓扑电路,实现对输入源的电压调节作用;同时组成后级三相全桥功率变换器拓扑电路,前级Boost DC‑DC变换器调节的输出电压作为后级三相全桥功率变换器拓扑电路的输入源,对无刷直流电机驱动进行供电,达到电机调速的效果;本发明不仅在硬件电路上实现集成拓扑,同时在系统控制方法上实现集成控制方式,本发明集成拓扑电路简单、体积小、对输入源电池电压适应性较高,适合应用于纯电动汽车领域,既可以驱动电动车运行,又可以在电动车发生制动情况下对制动能量的收集,节约能源,提高电动车行驶距离。
