The design of the current control loop in a boost PFC converter plays a significant role due to the large signal variations in the input waveforms. A predictive average current control law based on triangular modulation considering the converter non-idealities, time variation of waveforms and computation delays is proposed and validated with simulation and experimental results. A digital method for the boost inductance value estimation is also proposed which could be used with predictive current control laws. © 2018 IEEE.

Predictive Average Current Control Considering Non-Idealities for a Boost PFC Converter

Proceedings of 2018 IEEE International Conference on Power Electronics, Drives and Energy Systems, PEDES 2018

Boost type front end Power Factor Correction (PFC) converters are used to obtain a sinusoidal input current which is in phase with the input sinusoidal voltage while at the same time maintaining the output voltage constant. This front end stage is required to conform to harmonic norms. Unlike a DC-DC boost converter with small signal input variations about the quiescent operating point, the boost PFC converter is subjected to large signal variations in every half line cycle. In this paper, the nature of these large signal variations and effect of a linear controller in this converter is analyzed. Further, certain issues that lead to performance degradation in the converter are highlighted based on simulation results. © 2017 IEEE.
