S. Buso et al., SIMPLE DIGITAL-CONTROL IMPROVING DYNAMIC PERFORMANCE OF POWER-FACTOR PREREGULATORS, IEEE transactions on power electronics, 13(5), 1998, pp. 814-823
This paper presents the practical implementation of a fully digital co
ntrol for boost power factor preregulators (PFP's), The control algori
thm, which is simple and fast, provides a significant improvement in t
he system's dynamic performance compared to usual analog control techn
iques. The paper discusses the design criteria and the actions taken f
or the implementation of the digital control, which is performed by me
ans of a standard microcontroller (Siemens 80C166), The effectiveness
of the approach is assessed by experimental tests.
