摘要
Abstract
ZPW-2000A track circuits are critical safety devices used for continuously monitoring train positions and providing information on the availability of the sections ahead.They are widely used in the domestic railway systems of China.With the increase in energy consumption and the strengthening of environmental protection requirements,improving the efficiency of track circuit transmitters has become crucial.The current systems employ Class B push-pull amplifiers,which suffer from low efficiency,high power consumption,and severe heat generation.Digital amplifiers(Class D amplifiers),as a high-efficiency power amplification technology,can significantly enhance transmitter efficiency,reduce energy consumption,lower heat generation,and improve system reliability and equipment lifespan.This paper provides a detailed analysis of the working principles of Class D amplifiers and their application in track circuits and validates their performance advantages through Python simulations.关键词
