【摘要】 开关电源设计中,如何设计出性能稳定可靠的开关电源变压器是关键。本文从变压器设计的基本原理出发,提出了一种设计开关电源变压器的简便方法,即直接根据变压器的工作频率和所需输出的功率查表确定所需选用的磁性材料,从而确定变压器线包各参数;并对如何抑制电源变压器常见的噪声干扰进行了探讨。更多还原

【Abstract】 How to design the switching supply transformer which operate reliably is very important for design of switching supply. From the operating theory of switching supply transformer, the article put forward a simple and easy method to design it:according to operating frequency and output power, choose the magnetic cores which is necessary to design transformer so as to calculate parameter of coil; besides, discuss how to restrain the noisy.更多还原
