Abstract

Cable compensation has been used to compensate the voltage drop due to cable impedance for providing a regulated charging voltage in battery charger applications. However, modeling and design of cable compensation have never been analyzed before. In this paper, a novel cable compensation method, called cable minus compensation, is proposed and fully explored. Small signal analysis is used to analyze the system performances such as output impedance and stability. Based on the analysis, design criteria for the cable compensator and the feedback compensator are given. The analytic results are verified by the simulation results.
