摘要:

基于磁场耦合原理的无线输电系统中,高频电源作为发射线圈的激励源,其设计与实现对系统的整体性能至关重要。传统无线输电系统的激励源采用的是由整流和高频逆变构成的级联变换器,其结构和控制均较为复杂。提出了一种单级AC-AC谐振变换器,该谐振变换器通过一级功率变换,将低频交流电直接变换成无线输电系统所需的高频激励源,具有功率器件数量少、功率因数高等优点。通过实验,验证了所提出的变换器在串联-串联(SS)型谐振式无线输电系统应用中的可行性。

Abstract:

The design and implementation of the high frequency power supply, which offers a high frequency current to the primary winding, are of great importance in magnetic coupled Wireless Power Transfer (WPT) system. But the power supply, used in conventional WPT system, is comprised of rectifier and high frequency inverter, has the shortcoming of comparatively complicated structure and control. So, this paper proposes a novel single-stage AC-AC resonant converter. The proposed converter, converting the line source directly into high frequency source applied to WPT system via one stage conversion, has the advantages of less power elements and higher power factor. Experiments are carried out to verify the effectiveness of the proposed converter utilized in the WPT system with SS topology.

Key words: coupled resonant wireless power transfer, AC-AC converter, PFC
