| 摘 要： | 超声电机需要幅值较高的驱动电压，因此其驱动电路需要变压器升压。超声电机为非线性容性负载，需要进行阻抗匹配，并保持电压和相移恒定。采用推挽电路作为驱动器拓扑，分析了该驱动电路在不同性质负载情况下工作过程，结果表明驱动器在感性负载时的开关管损耗较容性负载时小，感性负载可提高驱动器效率和可靠性。给出LLCC谐振网络及其参数计算方法，通过理论分析和仿真证明了电机谐振电压和相移与驱动条件可解耦，且该LLCC谐振网络可使驱动电路的负载性质由容性转变为感性。用TRUM-60型超声电机进行实验，结果证明了该方法的有效性。

| Abstract: | High driving voltage is required for ultrasonic motors,so the driving circuit needs a transformer to boost voltage.Since the ultrasonic motor(USM) is a nonlinear capacitive load,a matching circuit is needed to keep the output voltage and the phase shift constant.Based on the switching circuit with push-pull topology,it was analyzed that the switching loss under inductive load is less than that under capacitive load,which will increase its efficiency and reliability.A novel LLCC resonant network was proposed... |
