可控硅是一种新型大功率半导体器件,广泛应用于交流调压电源中.我们所用的100KW、200KW高频焊接设备的是用500A和800A大功率可控硅来实现调压的.一般高频焊接电源可控硅调压多采用三相进线由三组反并联的可控硅控制的线路.又称外三角接法.如图1所示.
SCR is a new type of high-power semiconductor devices, widely used in AC power supply.We used 100KW, 200KW high-frequency welding equipment is 500A and 800A high-power SCR to achieve the pressure. Frequency welding power SCR SCR multi-use three-phase into the line by the three anti-parallel SCR control circuit. Also known as the outer triangular connection.
