An Integral Design of Ground Power Unit Supply for Aircraft Applications

A new ground power unit configuration is introduced in this paper. The architecture comprises a six-pulse rectifier with active current injection in the input stage to achieve high-performance conversion with low polluted ac spectrum, whereas the output voltage is synthesised with a neutral-point clamped inverter to attain an output with high quality that simplifies the LC filter development. The entire design of the static power converter is presented in this work, while simulation results are conducted for the validation of this proposal. A regulated output voltage with low distortion accomplishing the standards confirms the viability of this scheme.
