Single-ended Class E ZVS inverter is known as higher efficiency power converter with a simple design topology. However, the efficiency of the circuit is most influenced by the variations of the connected load, especially when dealing with ultrasonic transducer. This paper presents a design of high efficiency power converter for series resonance mode ultrasonic transducer in acoustics energy transfer applications. To enhance the performance of the circuit, the tuning procedure of shunt capacitor and series inductor are delivered and as a result, 0.191 W output power is able to be transmitted successfully with 95.5% power conversion efficiency.
