A large number of urban public transport infrastructures are powered by DC electrical energy that supplies power to light rail, metro trains and regional express train networks. For this purpose, a traction rectifier integrated into rectifier stations is used to convert alternative current into direct current.
The main utilised technology is a Graetz bridge equipped with one or more diodes connected in parallel, depending on the power to be supplied.
COMECA Power can offer a reliable and customised range of traction rectifiers for all the power and voltage requirements. For the same applications, COMECA Power also offers services of design and construction of IGBT inverters with energy recovery.
