提出了一种高效可行的一次侧控制方法,用于混合型储能(hybrid energy storage system
HESS)与无线电能传输(wireless power transfer
WPT)系统,该方法能够使系统在混合储能单元不同充电状态下动态维持最大功率传输以及E类功率放大器(class E power amplifier
Eop)的开关管处于软开关工作状态,确保混合型储能稳定高效地进行无线能量补充。系统拓扑由Eop、串联-串联(S-S)型WPT电路和HESS构成,基于对HESS不同充电模式下无线电能传输特性及Eop软开关特性的分析,提出了针对HESS无线充电的Eop最优频率追踪控制及Eop软开关占空比控制策略。该控制策略的优势是所有控制机构均位于发射侧,这样可有效减少接收侧储能单元的附加电路体积,提升系统的体积能量密度。最后,基于ZYNQ处理器搭建了实验样机,实验结果表明,该系统能够在混合储能不同充电状态及耦合条件下实现高效稳定的无线电能传输。
An efficient and feasible primary-side control method is proposed for the hybrid energy storage system(HESS) and wireless power transfer(WPT) system. This method can enable the system to dynamically maintain maximum power transfer under different charging states of the hybrid energy storage unit and keep the switching transistors of the Class E power amplifier(Eop) in a soft-switching operating state
ensuring stable and efficient wireless energy supplementation for the hybrid energy storage system. The system topology consists of an Eop
a series-series(S-S) type WPT circuit
and HESS. Based on the analysis of WPT transmission characteristics and Eop soft switching characteristics under different charging modes
the Eop optimal frequency tracking control and Eop soft switching duty cycle control strategies for HESS wireless charging are proposed. The key advantage is that all control mechanisms are located on the transmitting side
which can effectively reduce the volume of additional circuits in the energy storage unit on the receiving side and improve the volumetric energy density of the system. Finally
an experimental prototype is built based on the ZYNQ controller
and the experimental results show that the system can achieve efficient and stable wireless power transfer under different charging states and coupling conditions of the hybrid energy storage.
