Abstract

Increasingly, it is desired to operate electric fence energizers at higher power levels. This can be achieved by applying higher voltage output pulses from an electric fence energizer onto fence lines. However, and to comply with safety standards, this necessitates an increased level of voltage isolation between input and output parts of a mains-supplied electric fence energizer circuit. Therefore, low cost techniques to achieve high voltage isolation are required. Accordingly, this paper reports such a technique, based on integrating a contactless capacitive power transfer, CPT, circuit into the capacitor charging part of an electric fence energizer. Through compensation, reactive power drawn by the CPT circuit can be reduced, while assuring circuit operation as a current source. This is ideal for capacitor charging purposes, and energy transfer through appropriately separated CPT electrodes allows for high voltage isolation. The proposed CPT circuit is modelled. The results of modelling verify performance.
一种用于电动围栏充电器的无线电力传输系统
越来越多的人希望在更高的功率水平上操作电围栏励磁器。这可以通过在围栏线路上施加来自电动围栏激励器的更高电压输出脉冲来实现。但是,为了符合安全标准,这就需要在电源供电的电网激励器电路的输入和输出部分之间增加电压隔离级别。因此,需要低成本的技术来实现高电压隔离。因此,本文报道了一种基于将非接触式电容功率传输电路集成到电围栏激励器的电容充电部分的技术。通过补偿,可以降低CPT电路的无功功率,同时保证电路作为电流源的运行。这是理想的电容器充电的目的,和能量传递通过适当分离的CPT电极允许高压隔离。对所提出的CPT电路进行了建模。建模结果验证了性能。
