| Abstract |
Power quality is one of the challenging issues toward future more electric aircraft (MEA). In this paper, the authors presented a solution based on the application of a star-connected autotransformer based 24-pulse rectifier. Analysis and development of the proposed 24-pulse rectifier and the simplified MEA power system structure have been done in MATLAB/SIMULINK prior to the experimental implementation. Both simulation and experimental results are presented to validate the developed design procedure and the simulation models. The proposed autotransformer-based rectifier has
resulted in elimination of less than 23rd harmonic in the supply current. As a result, the supply current is near sinusoidal in shape with low total harmonic distortion (THD). Moreover, the power factor is also improved to nearly unity in the wide operating range of permanent magnet motor loads in MEA. Thus the proposed 24-pulse rectifier is ideally suited for retrofitting with existing motor drives in MEA. |
