Interaction between Passive Filter and High Power Cycloconverter Drive

This paper presents the study of dynamic interactions between passive filters and high power cycloconverters drives. The dynamic interaction considers the impact of connection and disconnection of passive filters operating in conjunction with high power cycloconverters. The inrush currents generated by filter connection affects the cycloconverter operation. The paper presents a detailed analysis based on results obtained from a real grinding mill plant with one SAG and two ball mill drives. The analysis presented in this paper includes the simulated model developed in MATLAB, transient analysis for connection and disconnection of the passive filter set, and recommendations to avoid transient interactions that affect cycloconverters drive operation.
