Developed Silicon & Sapphire Grower Heater Power Supply by IGBT.

Heater Power supply which we have developed has below specification.

1. This IGBT way jump in the PF(Power Factor) from 70% to 90%
2. Remove high frequency and make the under 10%
3. Compact Size compare with SCR
4. 50% light weight compare with SCR
5. Fast control speed
6. Minimize induction heating around cable
