Abstract |
In 1999 the production of a new multi-output auxiliary converter PJUT-2 started within the thyristorisation of the electric locomotives series 46 for the Bulgarian state railways. The PJUT-2 converter is responsible for transformation of single-phase line voltage (900 V, 50 Hz) into five three-phase outputs 3 x 400 V, 50 Hz as well as DC output 135 V, 50 A to supply a great number of consumers.
Up to present this type of converter has met all expectations and proved very reliable on thyristorised locomotives not only for Bulgarian (BDŽ) but also for Rumanian (CFR), Croatian (HŽ) and Macedonian (MŽ) state railways. |
