Abstract

This paper proposes a matched termination method to eliminate reflections of incident wave and harvest its energy at the end terminal of transmission line using time-varying circuit.
When the incident wave that the shape is known reaches the end of transmission line, time-varying circuit which is constructed by a half-bridge circuit with PWM control outputs a cancellation wave to cancel out a reflected wave and harvests its energy.
We designed the matched termination based on Laplace transform for a raised-COS pulse, and experimental results indicate that almost all energy of the incident wave was harvested.
