The advances made in power semiconductor technology have made possible new types of power controls for traction motors. These controls have opened the way for stepless performance, separately excited DC traction motors, AC brushless traction motors and regenerative braking. One of these controls, the DC-DC chopper is now in regular service on transit and railway systems such as BART, TEITO (Tokyo), Wuppertal (Germany), Belgium and Brazil. This paper explores the characteristics of chopper types, chopper circuits and performance of the series chopper and concludes with an economic evaluation of the chopper compared with the conventional resistor controller as well as AC motor inverter drives.
