DIRECT DIGITAL CONTROL FOR AC ELECTRIC LOCOMOTIVES

Hitachi has been developing a motor voltage regulator (MVR) having such new functions as self-check, failure memory, and monitoring by adopting direct digital control (DDC) using microprocessors in order to make electric locomotives more reliable, maintainable, and controllable. Improvements of control characteristics are reported in a bench test of a prototype MVR with DDC for ac electric locomotives (continuous rated output: 3000 kw).
