The Transfilter is a combination of a leakage-reactance magnetic structure and a capacitor, which is interposed between an ac thyristor voltage controller and the load, to filter the load current, to provide current-source characteristics, and to act as an isolation and impedance-level transformer. The Transfilter was originally developed to provide sinewave adjustable current up to 50 A at 60 Hz for an automatic power-system-relay tester.
