High-Frequency LLC Converter with Narrow Frequency Variations for Aircraft Applications
TL;DR: In this paper , the authors describe the design and implementation of a compact and high-frequency LLC converter with wide input voltage range (from 220 V to 320 V), output power ranges (from 250 W to 1.5 kW), high efficiency (over 96 % at full power), high power density (32 kW/dm), and narrow frequency variations (15 %).
Speed/Torque Ripple Reduction of High-Speed Permanent Magnet Starters/Generators With Low Inductance for More Electric Aircraft Applications
TL;DR: In this paper , an active damping technique is applied to the speed loop to increase the anti-disturbance capability and generate a smoother reference for the current loop, whereas an adaptive output voltage saturation limit is utilized to limit the peak value of current to prevent overcurrent and torque spikes.
