许多高频谐振逆变器拓扑的一个限制是它们对负载条件高度敏感。本文介绍了一种新的匹配网络，它大大降低了谐振逆变器和射频放大器的负载灵敏度。这些网络，我们称之为电阻压缩网络，用来大大降低调谐的射频逆变器在负载条件改变时看到的有效电阻的变化。我们探讨了这些网络的工作原理、性能特点和设计，并给出了实验结果。它们与整流器的组合形成具有窄范围阻性输入特性的RF-DC转换器也被讨论。在一台工作在100 MHz的DC/DC功率转换器上，演示了电阻压缩在谐振功率变换中的应用
A limitation of many high-frequency resonant inverter topologies is their high sensitivity to loading conditions. This paper introduces a new class of matching networks that greatly reduces the load sensitivity of resonant inverters and RF amplifiers. These networks, which we term resistance compression networks, serve to substantially decrease the variation in effective resistance seen by a tuned RF inverter as loading conditions change. We explore the operation, performance characteristics, and design of these networks, and present experimental results demonstrating their performance. Their combination with rectifiers to form RF-to-DC converters having narrow-range resistive input characteristics is also treated. The application of resistance compression in resonant power conversion is demonstrated in a DC/DC power converter operating at 100 MHz
