开关电源产品现在非常流行,人们在使用各种各类的开关电源的同时也开始逐渐重视开关电源的谐波干扰问题。开关电源可以说是无处不在,不管是航空航天、工业、民用还是农业。对开关电源的要求也是不尽相同,既要满足不同层次和类型的电压输出,也必须满足电流和功率的范围要求。本文对开关电源的状况、成果和存在问题进行研究。
Switching power supply products are very popular nowadays, when people use various kinds of switching power supply, people begin to pay more attention to the harmonic interference of switching power supply. Switching power supply can be said to be ubiquitous, whether it is aerospace, industrial, civil or agricultural. The requirements of the switching power supply are also different, not only to meet the different levels and types of voltage output, must also meet the current and power range requirements. In this paper, the state of the switching power supply, the results and the existence of problems to be studied.
