The power supply provides energy for the zone melting furnace of preparing high purity single crystal. It is the HF induction heating power supply with power supply technology on the input side to provide stable power output for zone melting furnace. It is with the merits of small volume, high power factor and low loss.
The power supply is composed of the power control cabinet and vacuum tube oscillatory power cabinet. In power control part, it adopts special thyristor power control unit, which is combined with advanced DSP and PLC control technology makes the power supply be with merits of high control accuracy and reliability. High power tube, as the core component of vacuum tube oscillatory power cabinet provides stable power output for zone melting furnace.
1. HMI: It adopts Siemens PLC + touch screen and is designed of full Chinese menu display. It works with simple parameter setting, and has a dual protection with double passwords to prevent wrong operation of parameters setting.
2. Advanced DSP control technology: The power unit control part adopts advanced digital processing technology. It works with merits of fast regulating speed and high control precision to ensure the zone melting furnace power control requirements during production.
