THYRISTOR CHOPPER FOR THE UNDERGROUND RAILROAD OF STOCKHOLM, SWEDEN

THYRISTOR-GLEICHSTROMSTELLER FUER DIE STOCKHOLMER U-BAHN

Since 1973 the underground railroad of Stockholm has operated electric multiple units (emu) with chopper control. These have proven well in many years of operating service. The value of possible energy recuperation by regenerative braking has been higher than expected despite the small number of thyristor controlled emu's on this line. Within a modernization program older trains are converted from resistance control to chopper control.
