The paper proposes a multi-frequencies,wide bandwidth and auto-recover protection power supply used to drive the ultrasonic motors (USM).The power supply uses the high frequency and high voltage amplifier to output the two-way voltage with 200 V of peak-peak value and its frequency is up to 300 kHz.Using virtual instrument of LabVIEW,it provides sine wave,square wave,triangle wave waveforms which the frequency,amplitude and phase can be adjustable.The power supply is also easy to incorporate with sensors to construct the control circuit of the ultrasonic motor.
