   Analysis, Modulation and Control of a Ground Power Unit for Aircraft Applications
By Beichen DUAN, Marco RIVERA, Patrick WHEELER, Javier MUNOZ [View]
[Download]

Abstract: This paper presents a PLECS-based simulation of innovative AC-AC converter configurations tailored for Ground Power Units (GPUs), addressing the critical demand for airport electrification, a cornerstone of sustainable aviation and ground operations. The proposed design incorporates a Current-Synthesized Power Factor Correction (CSPFC) rectifier, operating with a suitable harmonic injection technique, and proper modulation strategies. Simulation results demonstrate the system's effectiveness in mitigating issues such as harmonic distortion, voltage ripple, and other operational challenges, underscoring its potential to enhance performance and sustainability in GPU applications.

   Comprehensive Analysis of High Bandwidth Converters Based on SiC Technology for Automotive and Aircraft Applications
By Israel DA COSTA, Bernardo COGO, Lenin MORAIS [View]
[Download]

Abstract: This paper explores the influence of semiconductortechnology on the bandwidth of power converters,with a particular focus on the loss mechanisms ofSilicon Carbide (SiC) MOSFETs and the non-idealities ofswitching cells. A model for the harmonic content as afunction of switching frequency to evaluate the potentialbandwidth limits based on the total harmonic distortion(THD) of the output current is introduced. Given that therelationship between bandwidth and switching frequencyis directly proportional to the THD limit of the outputcurrent, it becomes crucial to investigate the temperaturelimitations and loss mechanisms of the components usedwithin the switching cell to ensure a viable converter. Bothsimulation and experimental results are employed to verifythe accuracy of loss models and evaluate the relationshipbetween THD and switching frequency, considering ripplecurrent, the effect of output inductance parasitic capacitance,the saturation of the magnetic core, as well as theimpact of dead time.

   Transition Control from Dual to Single Motor to Prevent Speed Reduction during an Open-Circuit Fault in a DC Power System

[Download]

Abstract: This study examined a tandem motor system for more electric aircraft (MEA). A method was proposed that, during a single motor's power loss, continuously outputs the necessary torque to maintain speed and suppress speed reduction compared with standard controls, achieved by directly modulating torque command distribution based on overmodulation detection.
