Paralleling, Interleaving, and Load Sharing

This is for the advanced reader. Part 1 focuses on derivations of the input and output ripple of a Buck converter and the corresponding RMS current stresses in the input and output capacitors. In Part 2, it is shown how multiple Buck power-trains can be combined to reduce the input and output ripple. This is called interleaving or multiphase operation. In Part 3, the inductors of interleaved Buck converters are coupled so as to provide significant improvement in efficiency and dynamic response to step loads. Detailed derivations follow with recommendations for the desirable coupling coefficient k. In Part 4, independent converters are combined to produce higher power outputs ...
