A microcomputer based control system, which is able to examine various phase control methods, was developed in order to find the optimum phase control method for an AC electric motor vehicle equipped with regenerative braking. This control system can perform the converting operation and regenerating operation of a multi-stage cascade thyristor bridge converter. Both the thyristor bridge and gate-turn-off thyristor bridges can be controlled. All phase control methods were tested with a small scale model power circuit (transformer primary voltage: 100 V, number of thyristor bridges: 10) and this control system. Test results showed that all intended phase control methods were well performed. Moreover, this system was applied to a half scale model power circuit (transformer primary voltage: 15000 V, number of thyristor bridges: 5, traction motor output power: 150 kW x 2). In the half scale model experiment, it was found that the improvement of the power factor could be made by the GTO thyristor bridge without the increase of Jp.
