Abstract

A novel phase control of a semi-bridgeless active rectifier (S-BAR) is investigated in order to utilize the S-BAR in wireless energy transfer applications. The standard receiver side rectifier topology is developed by replacing rectifier lower diodes with synchronous switches controlled by a phase-shifted PWM signal. Theoretical and simulation results show that the performance of the proposed S-BAR is appropriate for resonant converters that require power control at the secondary side such as contactless energy transfer systems. To confirm the performance of the proposed converter and control, experimental results are provided for a 1 kW prototype using 3, 6, and 9 inches air gap coreless transformer, which has dimension 2.5 by 2.5 feet, with 120 V input and the output voltage range of 0 to 95 V with a maximum efficiency of 94.4%.
