“…Besides, L s and C s also affect the impedance phase angle c 1 which can be calculated by (10). These two parameters should be chosen to fulfil the ZVS and ZCS requirements, that is, the (10) and (11). Among the qualified combinations of L s and C s , (14) can be applied to pick out a set of minimum sensitive parameters.…”

“…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.…”

“…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. A boost-type and half-bridge inverters with resonant circuits are invented in [11][12][13] to produce sine-wave output voltage. Nevertheless, the mathematical models of piezoelectric ceramic motors are complex and the motor parameters are time-varying and sensitive to the motor drive operating conditions [14,15].…”

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.
