Abstract

This study addresses the control of boost converters applied for power-factor correction in universal-line applications, using adaptive non-linear control based in passivity. The controller design is independent of the operating point and the gains of the control law have a clear physical interpretation. Discussion of the control approach with unknown load is provided. Robustness analysis of the proposed approach and comparison with standard approaches are made. The performance of the proposed power factor correction (PFC) rectifier was evaluated on an experimental 630 W universal-line PFC prototype.
