A switching circuit system based on FPGA is designed and implemented in this paper to provide high-frequency adjustable-phase voltages for the ultrasonic motor. For the existing drive systems of the ultrasonic motor, the bus voltage is usually 12V DC or 24V DC supporting by an external adapter, the driving voltages of the ultrasonic motor, however, are required to be boosted yet. Then, the step-up...
