Design considerations of direct current reactor in wave filtering applications

This paper discusses the design issues of a direct current filter reactor. The advantages of using such a device as a waveform filter include better regulation than the capacitor filter, and better utilization of the volt-ampere capacity of a rectifier transformer. To optimize the filter design, the characteristics of a rectifier circuit are presented. Various filtering techniques are reviewed. The fundamental concepts, the mathematical derivations and some special design procedures are described in detail
