Abstract:

This study's main idea is to design a high efficient capacitive power transfer (CPT) system consisting of a load network, a series resonance L-C circuit, and MOSFET. The MOSFET was used as a switch with a 0.5 duty cycle. The system consists of two main parts: the CPT system and the E-class power amplifier circuit design. To increase the efficiency of the wireless power transfer system E-class Power amplifier was used. The power telemetry has been realized by the copper capacitive plates with a 100 cm2 surface area. The efficiency of the CPT system is 82.1%. The throughput and input power of the system are 4.99 W and 4.1 W, respectively. Also, the switching performance of the E-class power amplifier circuit has been analyzed at 1.7 MHz frequency. The circuit was operated at its resonance frequency to increase the efficiency. Finally, the capacitive power transfer system has been designed with 81.2% efficiency at 1.7 MHz frequency and high SNR.
