摘要

Home energy management system (HEMS) dynamically regulates energy production and consumption to reduce energy usage costs and increase power efficiency. By combining wireless power transfer (WPT) technology with energy routers, this article proposes a new wireless energy router system for HEMS to realize omnidirectional cableless energy interconnection among various energy storage devices, such as portable electronics, electric vehicles, and energy storage stations. The proposed system contains an energy router and multiple transceivers. Each transceiver can be charged and discharged through two independent power channels with different operating frequencies. First, two orthogonal router coils with LCC compensations work at two operating frequencies, enabling omnidirectional power transmission with the transceiver coils. Accordingly, a dual-frequency constant-current compensation network is proposed for the transceiver circuits to offer constant coil current operation. Furthermore, a decoupled phase-shift control with a power flow tracking algorithm is introduced to achieve independent power control for each transceiver. Finally, a parameter design procedure is developed, where a SIC- mosfet prototype with three transceivers is used to verify the effectiveness of the proposed system. Experimental results prove that the transceivers can get energy interconnection from all directions, and the power flow can be regulated independently from the transceiver side.
