This paper presents some of the important design issues of traction converter for three phase AC locomotive. The analytical approach is required to select appropriate components which will make the system more reliable, stable with minimum power loss. The mathematical approach required in the design of each component is presented. The main components of TC such as IGBTs, Driver circuit, heat sink, precharging resistor, DC link capacitor, resonant filter, bleeder resistors, earth fault resistors, braking chopper are discussed in this paper. The behavior of each component under variation in power supply and supply frequency are discussed. The analysis presented in this paper is very much useful for a designer while designing a converter inverter system for a vehicular system. The control strategy adopted for front end converter is discussed and simulated results using PSIM is also presented.
