iNAS-A series active power filter in the furnace Sapphire Dan Changjing successful application . 
Crystal growth furnace power three-phase full-controlled bridge rectifier circuit the AC to DC rectifier , the flat wave reactor , became a constant DC current source , and then the single-phase inverter bridge , the DC current is about reverse into 7KHz single-phase frequency currents. Load from the induction coil and the compensation capacitor , which connects to the parallel resonant circuit is inductive furnace . In the production process a large amount of harmonic currents in the 2,4,5,7,8 harmonics , where about 70% of the second harmonic . Adjusting the power system and the harmonic content of the current RMS will have a corresponding change in the current of 60A , the voltage distortion rate of 7.9% , current harmonic distortion rate of 110% ; at a current of 150A , the current harmonic distortion 76% . Current harmonics at 60A ~ 120A or so. Furnace put a British Nast electrical iNAS-A-150A - 03-380 active power filter for harmonic control , the voltage distortion rate dropped to 2.8% current distortion rate dropped to 3.9%.
iNAS-A put into use dramatically improve power quality crystal growth furnace to improve the stability of the power to improve the yield of the crystal , while protecting the normal operation of the equipment . In iNAS-A input before , only to open simultaneously three crystal growth furnace , iNAS-A input , you can also turn on all crystal growth furnace .
