高频变压器工作原?br />
变压器是变换交流电压、电流和阻抗的器件，当初级线圈中通有交流电流时，铁芯（或磁芯）中便产生交流磁通，使次级线圈中感应出电压（或电流）。变压器由铁芯（或磁芯）和线圈组成，线圈有两个或两个以上的绕组，其中接电源的绕组叫初级线圈，其余的绕组叫次级线圈?br />
高频变压器用?br />
高频变压器是工作频率超过中频?0kHz）的电源变压器，主要用于高频开关电源中作高频开关电源变压器，也有用于高频逆变电源和高频逆变焊机中作高频逆变电源变压器的。按工作频率高低，可分为几个档次?0kHz- 50kHz?0kHz-100kHz?00kHz?00kHz?00kHz?MHz?MHz以上。传送功率比较大的情况下，功率器件一般采?IGBT，由于IGBT存在关断电流拖尾现象，所以工作频率比较低；传送功率比较小的，可以采用MOSFET，工作频率就比较高?/p>
<p> <span style="FONT-FAMILY: Arial">小编提醒您，在设计高频电源变压器的时候，一定要从多方面资料进行参考，这样它设计得最有价值。本篇文章由深圳晨飞电子技术团队提供，转载请注明。网址：http://www.chenfeipower.com?/span><span style="FONT-FAMILY: Arial"> </span></p>
