COMPARISON OF A THYRISTOR-RECTIFIER WITH A HYBRID FILTER AND A CHOPPER- RECTIFIER FOR HIGH-POWER, HIGH-CURRENT APPLICATION

This paper presents a comparison of two rectifier-systems for high-power, high-current application. 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 to improve the power factor and reduce current THD. Another solution involves a multi-pulse diode rectifier followed by a multi-phase DC chopper (chopper-rectifier). A comprehensive system level approach is chosen for comparing a 12-pulse thyristor-rectifier with a hybrid filter and 12-pulse diode rectifier with a multi-phase DC chopper. The comparison covers system performance, efficiency, size and cost for an industrial load with given system specifications.
