电子装备电磁兼容性与电源设计

论文通过分析开关电源的工作原理,指出了电磁干扰形成的主要原因,介绍了采用交流分布式供电体制的电子装备解决电源线传导发射（CE101）问题的基本解决措施,提出了集中加分布式供电的二次供电体制,以降低输入电流的谐波电流以及对供电系统产生的不利影响,有效解决电源功率大于1KVA的电子装备中电磁兼容性测试项目CE101的超标问题.

Power Supply and EMC of Electronic Equipment

Aiming at the EMC problems of the naval equipment system brought by switching power supply and distrib- uted AC power system, a new power system is proposed, which includes a concentrative power system and a distributed power system. Both theoretic analysis and experiments prove that the superscale of CE101 on more than lkVA electronic e- quipment is greatly reduced in the new power system. It can also decrease the input harmonic current and the harm of the power supply system brought by the electronic equipments. At the same time, it increases the convenience for thermal de- sign, reliability and safety of the system.
