Abstract

This paper analyses a multi-output half-wave semi-synchronous rectifier (SSR) by using a uniform field transmitter. The presented multi-output half-wave rectifier topology is achieved by replacing half-wave rectifier lower diode with a synchronous switch and regulation by a phase-shifted PWM signal. The front end transmitter is intended to generate uniform magnetic fields over the coil area. To confirm the performance of the multi-output system, experimental results are provided by using funnel shaped air gap wireless transmitter (the radius of 20 cm) for which input 120 V with two receivers (the radius of 5 cm).
