This paper presents a comparison of two rectifier-systems for high-power, high-current appli- cation. The most popular choice of circuit topology for this type of application is a multi-pulse thyristor rectifier. Active or passive filters are added to the thyristor rectifier for improving the power factor and reducing current THD. Other type of solution comprises of a multi-pulse di- ode rectifier followed by a multi-phase DC chopper (chopper-rectifier). A comprehensive sys- tem level approach is chosen for comparison of 12-pulse thyristor rectifier with a hybrid filter and 12-pulse diode rectifier with a multi-phase DC chopper. Comparison is carried out in terms of system performance, efficiency, size and cost for an industrial load with given sys- tem specifications.
