High-power static induction transistor (SIT) is a high-power electronic devices, the same as its symbol and the transistor, the role of high-frequency machine is also similar, but it is mainly used in high-power converter or conduction control applications, it has the following characteristics: having a "positive turned" feature, when the positive gate voltage is "0 V", SIT in the conductive state, while when applying a negative gate voltage, then in the off state. Fast switching speed for high frequency band. Is a high input impedance voltage-controlled device producing high-frequency machine, so use a smaller drive power can control a large success. Frequency induction heating equipment, also known as high-frequency heating machine, high frequency induction heating machine, in China called "high-frequency induction heating power supply" or "high-frequency power" in Guangdong, Taiwan, also known as high-frequency induction heating machine high frequency machine repair, depending on the workpiece and applications, it is called the induction heating equipment, super-audio frequency induction heating equipment. It is mainly for metals induction heating (non-contact); the inverter components for general use SCR, vacuum tubes, etc; the use of SCR technology as the inverter element is very mature and has already started, and power can be KW do more than a few hundred, but the frequency generally 10KHZ below. When using vacuum components as inverters, frequency and power aspects of high frequency machine processing can be done, but it consumes too easily damaged. IGBT and MOS tube is a high frequency component industry on new applications, respectively, can be replaced by thyristors and vacuum tubes. I produced the ultra-audio frequency induction heating equipment used in all new IGBT-based circuit elements, it can do the most power, voltage regulation power heating fast, small, convenient and safe to install and operate, easy to automate or in connection with connection and so on.
