Design and Analysis of the Analog Channel Insulation in On-Line Test
摘要
Abstract
Considering the effect on equipment working circuit from the current shunt of analog channel in online test, the insulation method is studied and the insulation circuit based on Darlington emitter follower network is designed. With the analysis of the emitter follower network LF and HF model, the LF and HF input impedance is computed and the second order damping model is deduced. The feasibility of the insulation circuit is verified after the simulation of the circuit and practical experiments, associating the input and output structure of equipment.关键词
