THE REGENERATIVE BRAKES OF THE THYRISTOR LOCOMOTIVE EE 3/3 II OF THE SWISS FEDERAL RAILWAYS

In 1972 the dual-frequency shunting locomotive Ee 3/3 II, No. 16502 of the Swiss Federal Railways was equipped with a new static convertor-type regenerative brake developed by Brown Boveri. The special feature of this brake is the use of the traction motor with combined differential excitation and a de-exciter. Neither a high-speed d.c. circuit-breaker nor a limiting resistor in the traction motor circuit are required to protect the static converter and traction motor in the case of inverter commutation failure. This article describes the steady and transient behavior of the main circuit during braking.
