Simulation of Class D resonance inverter for Acoustics Energy Transfer applications

Abstract

Power conditioning stage of an acoustics energy transfer (AET) is a key step in determining the overall efficiency of the AET system. On the transmitter side, it needs to drive the device at the exact operating frequency meanwhile at the receiver side, it need to able to extract maximum power through interfacing with PZT transducer. This paper will study and simulate the Class D parallelresonance inverter for the transmitter side of an AET system. The aimed of the circuit is to produce around 80 mW power at the operating frequency 416 kHz for implantable applications. The Proteus Software used as simulation platform with peripheral interface controller (PIC16F877A) as pulse width modulation signal generator. The pulse width modulation (PWM) used to generate switching signal for MOSFET IRF5852TR gate in the circuit. Keywords-Half-bridge Class D inverter; low power applicationsI.
