At control outputs below 100%, analog thyristors cause high harmonic distortion on the power supply and a poor power factor, as well as a significant decline in energy efficiency
Due to poor power factor, energy is wasted in the system, leading to unnecessary extra costs for filters and capacitor banks
Analog thyristors cause difficulties in the control of the furnace heaters. Temperature stability and accuracy cannot be achieved causing process repeatability issues
