摘要
高频开关电源是目前使用最广泛的一大类电源,由于电磁兼容性的标准以及出口产品性能的要求,电源新产品的电磁兼容性能设计面临严重挑战。文章阐述了相关传统技术的不足,新的实用技术原理和新技术研究的发展动态,并作了评述。文中还特别指出,混沌调频将会成为抑制EMI的一种实用技术。
High frequency switch-mode power supply is the most popular power supply at present, due to the standard of EMI and the performance requests of export product, the EMI design of new power supply product is faces a severity challenge. This article expound the insufficiency of related traditional technology, the principle and develop trend of new technology and gives comments on it. It is particularly points out that the chaos frequency modulation will be a utility technology to restrain EMI.
