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.

“…However, this controller cannot maintain the circuit to be fully tuned so the maximum power that can be transferred may be significantly reduced if the circuit parameter varies. It also allows the short circuit current of the pick-up coil to flow through the semiconductor switch, which causes high power losses particularly under light loading conditions [12].…”

The present study proposes a simple fuzzy PID controller combined with directional tuning control for regulating the output voltage of a wireless power pick-up. The output voltage is controlled by changing the equivalent inductance of a magnetic amplifier by a suitable value. Accurately determining the step-size of the inductance variation is an important task of this research to enable satisfactory control. The proposed controller essentially regulates the output power with logical step changes of the inductance of the magnetic amplifier, which allows the power pick-up to achieve full-range tuning/detuning operation in maintaining the output voltage to be constant. The effectiveness of the proposed controller has been verified by simulation study under a variety of conditions, and superior results have been obtained compared to a classical directional tuning controller which modifies the equivalent inductance by a fixed step-size. Index Terms-Contactlesspower transfer, Fuzzy control, Magnetic amplifier, Power flow control, Resonant power converter, Wireless power transfer.

An implicit generalized minimum variance type adaptive controller has been designed for regulating the output voltage of a wireless power pick-up. The parameters of this controller are directly estimated without explicitly identifying system parameters and therefore it offers significant advantages over explicit type adaptive controllers requiring process parameter estimation. The performance of this controller has been illustrated via simulations. Results of simulation under various conditions demonstrate that the proposed controller can achieve full-range tuning control and successfully regulate the output voltage under system parameter variations.
