Design of WPT System Based on Interleaved Boost Converter

With the improvement of technology, demand for electrical power continues to deepen. Wireless Power Transfer (WPT) technology can transmit without using physical media such as cables, and it has advantages isolation, convenience, safety. At present, miniaturization secondary side is an emerging trend WPT systems, which analyzed in this paper. By introducing interleaved boost converter front stage, DC bus voltage primary increased, loss reduced, system efficiency improved. same time, self-inductance sides loosely coupled transformer designed meet stress requirements passive devices realization a closed-loop system. Finally, with input 100 V, output V transmission 500 W built. The distance 170 mm, lateral offset 200 mm vertical mm. After sides, be stabilized at reach 90.1%, proves feasibility strategy effectiveness control.
