With historically lower initial and operational costs, the zero-cross SCR / thryistor power controller provides robust on-off control for heaters and inductively matched loads such as transformers in the case of electric boosting of glass furnaces. Turning power on and off at the instant of zero voltage also reduces the total harmonic distortion caused by the controller which reduces electromagnetic interference and utility imposed charges for operating low power factor equipment
By individually regulating the conduction angle of each half-cycle, phase angle regulation provides precise control of AC power. Controlling SCR / thyristor turn-on has the advantage of limiting current, providing in-rush current control for large inductive loads, and regulating the average output voltage and AC bias.
