“…Accordingly, sine-wave voltages are beneficial to actuate the motors. Several researches are suggested for piezoelectric motor driving schemes [9][10][11][12][13]. In [9,10], sine-wave signal is generated by voltage-controlled oscillator and fed into power amplifiers to provide the needed frequency and voltage amplitude.…”

This study addresses the design and analysis of a single-stage high power factor half-bridge driver, which is composed of a half-bridge resonant inverter and a buck-boost converter, for a linear ultrasonic motor (LUSM). LUSMs have found their applications in miniaturised actuators and precision position manufacturing industries due to their merits of miniaturisation and high resolution. The triggering signals of both the active switches are generated using asymmetrical pulse-width modulation technique to achieve zero-voltage switching and zero-current switching using proper designed circuit parameters. Then, liquid chromatography resonant technique is adopted to produce 39.6 kHz sinusoidal voltage output. A laboratory-made circuit is built to test the circuit topology. Satisfying results are obtained to verify the validity of the proposed topology.
