A new topology of resonant inverter including a piezoelectric component

Abstract : This document introduces a new resonant inverter topology based on the Φ2 inverter. This new topology uses multiple resonance to pass fundamental and third harmonic at the switch terminals by filtering second harmonic with a piezoelectric component. This helps to reduce the voltage stress on the switch. Adding a piezoelectric resonator allows a better frequency stability and a better performance than a classic LC circuit. The structure and the design of the topology are described. Experimental results demonstrating the feasibility of the topology and a comparison with simulation results are done. The prototype works at 1.4MHz for an input voltage of 20V, an AC output voltage of 20V and an output power of 15W.
