摘　　要：针对宏微超声电机驱动系统内部电路需求多路相互独立的高稳定精度电压,设计了逻辑链路控制(logical link control,简称LLC)变换器+开关型集成稳压两级结构的多路独立输出稳压电源。采用LLC变换器将220V交流电降压变换为多路输出,主功率用闭环控制实现高精度稳压输出,其他辅助输出用高效开关型MP1584降压稳压电路实现二次稳压输出。用设计的电源、宏微超声电机、宏微驱动器、光栅尺及激光测振仪构建了宏微超声电机驱动控制系统。试验结果证明,本电源解决了传统单级多路输出电源存在的交叉调整率问题,能提供±1%内的稳定电压,整机效率≥80%,且线路简单、体积小,工程设计上易于实现;优化了宏微超声电机驱动控制系统的体积,提高了效率和可靠性。The internal circuits of macro-micro ultrasonic motor(MMUSM)drive system require multiple independent different amplitudes,high stability and precise power supply.A multiple independent output power with logical link control(LLC)converter and switch integrated voltage regulator is designed.The LLC converter is used to convert alternating current(220 V)to multiple output.The main power is closed-loop controlled to achieve a high-precision regulated output.The other auxiliary output is regulated by a high efficiency MP1584 Buck-regulator.Its drive control system includes a power supply,MMUSM,a macro-micro driver,agrating ruler and a laser scanning vibrometer.The experimental results show that this power supply solves the cross regulation problem existing in the traditional single-stage multi-output power supply.It can provide a stable voltage within±1%,and the efficiency is≥80%.It also has a simple circuitand a small size,which is easy to implement in engineering design.In addition,the reliability,the volume and the efficiency of this MMUSM drive system are optimized.
