A three phase AC main power source is fed into a rectifier and filter combination to create a smooth DC power source. This DC source is then fed into an integrated gate bipolar transistor (IGBT) full wave bridge circuit where it is converted into a high frequency AC waveform.
The SMPS switch module is assembled on a steel panel that occupies roughly the same space as an existing SCR module. Mounted on a common heat sink are the rectifiers, the filter assembly, IGBT Modules, and IGBT Gate drivers.
The Ador MFPS controller outputs a predetermined frequency to fire the IGBT’s. Feedback control uses mA and KV feedback for voltage, Current and spark/arc control.
