SERVICE IMPROVEMENT OF THE QUENCHABLE NONSYMMETRIC BRIDGE CIRCUIT IN MULTIPLE-UNIT TRAINS TYPE ET 420

BETRIEBSERTUECHTIGUNG DER LOESCHBAREN UNSYMMETRISCHEN BRUECKENSCHALTUNG (LUB) IN DEN TRIEBZUEGEN ET 420

The electric multiple units series ET 420 for West German urban rapid transit systems are equipped with phase angle control, which is operated as sequence control of two converter bridges in order to diminish the reactive power requirements. Some years ago three multiple units had been additionally equipped with a quenching circuit at one of the bridges in order to improve the power factor. It is shown how this installation has been gradually improved to meet operational requirements.
