Abstract :
The advatages and disadvantages of seven thyristor choppers which are cerrently used by traction equipment manufacturers are evaluated. The possible modes of circuit operation are discussed. The ratings of the components and power devices are determined for a typical application. The switching losses are also estimated and circuits are compared in terms of ratings, number of devices, fuse and heatsink requirements.
