This paper presents practical aspects related with the operation, compensation and protection of high power cycloconverters used in mining industry. Practical recommendations related with start-up, operation characteristics and un-expected shut-down process is described. Fuseless characteristics of modern cycloconverters are also discussed. Relevant current waveforms associated with the starting of...
This paper presents a filter scheme composed by passive and series active power filters specially designed to compensate fundamental reactive power (with passive filters) and current harmonics (combination of passive and active). Low frequency current sub and inter-harmonics generated by cycloconverters are eliminated with an active power filter connected in series to a C type passive filter. Current...
This paper presents a design method for passive filters used to compensate power factor and current harmonics generated by high power cycloconverter drives. The paper includes the analysis of different passive filter topologies effectiveness (band-pass, high-pass and C type), a procedure to calculate filter parameters, tuning frequency selection, and reactive power distribution. The passive filters...
