The use of precalculated duty cycles for power factor correction leads to a significant simplification of the design and a reduction of the final cost. There are previous proposals for handling non-nominal conditions such as input voltage or load variations. However, there are no proposals for handling input frequency variations, which have an important impact in the power factor. This paper measures this impact and includes a simple loop to handle the variations of the input frequency. The results show that the introduction of this loop keeps the power factor values around those obtained in nominal conditions.
