<p>我们常见的高频变压器是工作频率超过中频（10kHz）的电源变压器，它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?/p>
<p>我们可以很肯定的就是<strong>高频变压?/strong>是开关电源最主要的组成部分。开关电源中的拓扑结构有很多。比如半桥式功率转换电路，工作时两个开关三极管轮流导通来产生100kHz的高频脉冲波，然后通过高频变压器进行变压，输出交流电，高频变压器各个绕组线圈的匝数比例则决定了输出电压的多少?/p>
