摘要
比较电路在增强型罗兰固态发射机电路中使用广泛,尤其在幅度、定时控制以及故障检测中,比较器电路往往起到重要作用,是固态发射机输出稳定、精准的导航授时信息的关键。掌握这些典型电路对于提高发射机运维能力很有帮助,文章针对不同比较电路的典型应用场景展开分析,并利用LTspice软件对分析结果进行了仿真验证,验证结果显示该方法对于开展板级电路故障诊断和维修有一定的指导意义。
Comparison circuits are widely used in enhanced-Loran Transmitter,especially in amplitude,timing control and fault detection circuits,which often play an important role and is the key to output stable and accurate navigation timing signal of solid-state transmitter.It is helpful to master these typical circuits to improve the operation and maintenance ability of transmitter.In this paper,the typical application scenarios of comparision circuits are analyzed,and the results are verified by LTspice,the simulation result show that this method has a certain guiding significance for development fault diagnosis and maintenance of board level circuit.
