超声电机驱动电源整流斩波电路设计

超声电机（简称USM）是微型电机领域中的一种新型电机，具有控制精度高、体积小、响应快、转速低、不受电磁干扰等诸多优点，在微型机械、精密仪器、航空航天、汽车、医疗及军事等领域被广泛应用。但由于USM具有特殊的结构和运行机理，在USM驱动控制系统中，一般是通过控制斩波电路控制USM的运行速度，所以斩波电路的优劣直接影响电机的运行性能。本文根据USM驱动电源的特点，设计TUSM驱动电源整流和斩波电路：最后通过电路仿真实验，满足了设计的要求。

Ultrasonic motor （USM） is a new motor in the micro-motor field, with high control accuracy, small size, fast response, low revolving speed, anti-electromagnetic interference, and many other advantage. It is used in micro maahiner~ precision instruments, aerospace, automobile, medical and military fields widely. But USM has a special structure and operating mechanism. In the USM driving control system, the operation speed of the USM is controlled by controlling the chopper circuit, so the advantages and disadvantages of the chopper circuit have a direct impact on the performance of the motor. According to the characteristics of USM driving power supply, this paper designs the rectifier and chopper circuit of USM drive power supply; Finally, through the circuit simulation experiment, the requirement of the design is satisfied.
