APPLICATION OF THYRISTORS IN RAILWAY TECHNOLOGY: CONSEQUENCES AND REMEDIES. CHOPPER CONTROL SYSTEMS

Within the scope of studies concerning possible interference induced in signalling and telecommunication installations caused by chopper-controlled motive power units, the Committee thought it useful to make a comparison between the various control systems. The present report contains a comparison of the control of choppers by varying the pulse frequency or pulse duration and it describes several possible solutions during the starting process. With a view to the high powers usually installed in motive power units, and, above all, with a view to the signalling and telecommunication installations on the railway administrations, the application of choppers operating at fixed frequencies is considered desirable.
