全固态发射机低压电源系统的电磁兼容性

Electromagnetic Compatibility of Solid-state Transmitter Low-voltage Power Supply System

全固态发射机以其整机效率高、各项指标好、运行稳定等诸多优点已经成为行业主流。但是,它在抵御外部干扰方面较传统发射机并不占优势。文中阐述了EMI(电磁干扰)与EMC(电磁兼容性),分析了浪涌及全固态发射机低压电源系统电磁兼容性的重要性。并以DX-600型大功率DAM全固态广播发射机的低压电源系统为例,详细阐述了提高全固态发射机低压电源系统电磁兼容性的措施及效果。

Because of solid-state transmitter＇s technical guide lines, efficient, stability, and other advantages, the transmitter has been widely used. However, its suppressed external interference has no advantage over traditional transmitters. This paper explains the electromagnetic interference and electromagnetic compatibility, it analyzes surges and the importance of low voltage power system＇s electromagnetic compatibility. This paper thoroughly describes the improvement measures for the low-voltage power system electromagnetic compatibility of solid-state transmitter and their effects with the example of DX-600 DAM high-power solid-state radio transmitter low-vohage power supply system.
