In this study, a novel phase controlled of single switch active rectifier (S-SAR) is investigated for applications in wireless energy transfer. The proposed rectifier structure is based on the connection of controllable single switch thorough full bridge rectifier and regulation by a phase-shifted PWM signal. Theoretical and simulation results show that the performance of the proposed active rectifier topology is appropriate for resonant converters and secondary side controlled structure requiring power control at the secondary side such as contactless energy transfer systems. A 1 kW laboratory prototype system is designed to validate the proposed topology in terms of power and efficiency. Experimental results are provided for various loads using 8 inches air gap coreless transformer, which has dimension 2.5 by 2.5 feet, with a 120 V input and a maximum efficiency of 93 %.
