| 摘 要： | 根据超声电机的容性负载特性,提出了利用LC进行谐振升压的无变压器式驱动电路.分析了输出信号中各次谐波幅值和能量比与驱动信号占空比和谐振周期之间的关系,据此提出了驱动电路的设计准则.应用此电路驱动直径为5mm的超声电机,输出电压峰峰值达200V以上,电机运转良好,证明了此电路对于驱动小功率超声电机的实用性和可靠性,为驱动器的进一步集成化奠定了基础.

| Abstract: | According to the capacitive characteristic of ultrasonic motor,a non-transformer driver scheme for ultrasonic motor using LC resonant is proposed in this paper.The circuit is theoretically analyzed and verified by simulation.The relationships of the amplitudes and energy efficiency of the harmonic wave for the output voltage with the driving duty ratio and resonant cycle number are analyzed in details.Based on this,the design criteria of the circuit are established.The circuit is applied to a 5mm ultrasonic motor.The output voltage is above 200V(Vp-p),the motor works well.It is proved that this circuit is both feasible and reliable for the drive of small-power USM,which makes it easier for the driver to realize integration. |
