电磁环境下的直流电源研究

Study on DC Power Electromagnetic Environment

科技的飞速发展,使得电源设备得到了非常广泛的应用。我们的生活也随之发生了翻天覆地的变化。生活中所有的电子、电气设备都离不开电源,其质量和性能的好坏直接影响着我们的生活质量。电源可以简单的分为交流电源和直流电源两种,其中直流电源为各种电子设备的能量来源,尤其是智能硬件不可缺少,其发展前景是非常好的。发展到今天,电源技术已趋于成熟,随着人们对电源各方面要求的提高,现在的电源已经是有较强功能的集成模块,不再是以前那个简单的电子线路了。不过,科技的发展各种电气化设备的普及,电子设备间的相互干扰给电源技术带来了新的挑战电磁干扰。直流电源将市电220V/50Hz电压通过变压器降到需要的交流电压,再经过整流变成脉动的直流电,最后通过滤波器和稳压器变成直流电压。

The rapid development of science and technology, the power equipment has been widely used. Our life has also under-gone changes in turn the world upside down. All electronic and electrical equipment in life are inseparable from the power supply,its quality and performance directly affects the quality of our life. The power supply can be simply divided into two kinds of ACpower supply and DC power supply, the DC power supply for electronic equipment, energy sources, especially the intelligent hard-ware is indispensable, its development prospects are very good. Until today, the power technology has become mature, with peopleof all aspects of the power requirements increase, the power supply is now integrated module have strong function, is no longer thesimple electronic circuit. However, the development of science and technology popularization of a variety of electrical equipment,the mutual interference between electronic devices has brought new challenges to the electromagnetic interference of power supplytechnology. DC power electric 220V/50 Hz voltage to AC voltage required by the transformer, then rectified into direct current rip-ple, and finally through the filter into the DC voltage regulator.
