Hybrid-Frequency Interleaved Control Strategy
- Language
Double-Frequency converters offer fast response and lower cost but suffer from highly complex control strategies and lower power quality with parameter uncertainties. In this paper, an adaptability hybrid-frequency interleaved control strategy is proposed, which not only can simplify the high-frequency control loop but also improve the power quality performance under parameter uncertainties conditions. A totem pole based double-frequency AC/DC converter is selected as the case study, and the PLECS simulation platform is built. The results indicate that the proposed strategy can simplify the computation burden for high-frequency control loops and achieve over 30% THD performance reduction under parameter uncertainties conditions.
