| Summary: | The increasing adoption of power electronics devices in the more electric aircraft (MEA) industry brings the need for advanced power quality solutions to ensure stable operation under challenging conditions such as unbalanced grids, unbalanced DC loading, arc faults, and variable grid frequencies. This study introduces a hybrid controller for Vienna rectifiers to overcome the addressed power quality issues. The proposed controller strategy integrates Hysteresis Current Control (HCC), a Second Order Generalized Integrator-Phase Locked Loop (SOGI-PLL), and a Proportional Integral Resonant (PIR) controller, collectively improving grid synchronization, enhancing power quality by minimizing total harmonic distortion (THD), and ensuring stable operation during grid disturbances. The proposed strategy achieves a <inline-formula> <tex-math notation="LaTeX">$THD_{i}$ </tex-math></inline-formula> of 2.24%, significantly lower than the 4.74% reported in comparable studies, while maintaining compliance with the requirements of MIL-STD-704F. Extensive simulations validate its effectiveness, demonstrating robust performance in scenarios with unbalanced grids, unbalanced loading, and series arc faults, alongside maintaining minimal DC voltage ripple and near-unity power factor. The findings represent a significant advancement in power electronics, offering a reliable and efficient solution for dynamic and fault-prone electrical systems. |
