电磁炉、变频器、逆变器、UPS电源、EPS电源、开关电源、电机控制、变焊机、固态继电器、有源滤波器、风力发电设备、工业传动装置、电梯或传动设备、机车与列车用电源、电能表、照明电器等各种产品上。<br/><img

结的四层结构的大功率半导体器件。实际上，可控硅的功用不仅是整流，它还可以用作无触点开关以快速接通或切断电路，实现将直流电变成交流电的逆变，将一种频率的交流电变成另一种频率的交流电，等等。可控硅和其它半导体器件一样，其有体积小、、稳定性好、工作可靠等优点。它的出现，使半导体技术从弱电领域进入了强电领域，成为工业、农业、交通运输、军事科研以至商业、民用电器等方面争相采用的元件。<br/><img src="http://oss10.huangye88.net/live/2023/08/25/1dddda2558e84e6e34f88c19d440da1b.jpg@750w_750h_90Q" /><br/>可控硅的特性：常用的有阻容移相桥触发电路、单结晶体管触发电路、晶体三极管触发电路、利用小晶闸管触发大晶闸管的触发电路，等等；<br /> 可控硅的主要参数有：<br /> 1、 额定通态平均电流在一定条件下，阳极---阴极间可以连续通过的50赫兹正弦半波电流的平均值；<br /> 2、 正向阻断峰值电压：在控制极开路未加触发信号，阳极正向电压还未超过导能电压时，可以重复加在可控硅两端的正向峰值电压。可控硅承受的正向电压峰值，不能超过手册给出的这个参数值；<br /> 3、 反向阻断峰值电压：当可控硅加反向电压，处于反向关断状态时，可以重复加在可控硅两端的反向峰值电压。使用时，不能超过手册给出的这个参数值；<br /> 4、 触发电压在规定的环境温度下，阳极---阴极间加有一定电压时，可控硅从关断状态转为导通状态所需要的小控制极电流和电压；<br /> 5、 维持电流：在规定温度下，控制极断路，维持可控硅导通所必需的小阳极正向电流。许多新型可控硅元件相继问世，如适于高频应用的快速可控硅，可以用正或负的触发信号控制两个方向导通的双向可控硅，可以用正触发信号使其导通，用负触发信号使其关断的可控硅等等。</p></p></div> </div> <div class="list-desc h"> <ul>
