摘要
文章介绍当前汽车工业被广泛采用的高速CAN总线技术在电磁兼容测试中的负载阻抗配置的解决方案,并特别结合汽车企业标准DC11225,介绍了在电磁兼容试验中使用光电隔离器接入高速CAN总线时,对光电隔离器的内阻设置要求,为电磁兼容测试中测试设置提供参考。
CAN BUS is a now-rising technology which is widely used within automotive industry .This article introduces the proper loading impedance matching method of CAN bus network in EMC testing, and suggests a solution for CAN bus fiber optical connection and fiber optical device internal impedance setting per Chrysler specification DC11225. The suggestion can be used as a guideline in the EMC testing practice.
