Abstract :
This paper deals with the design, control and implementation of a 10 kVA three-phase ground power supply unit (GPU) for aircraft servicing. Instead of a classical back to back converter configuration, a 3-phase to 3-phase direct AC-AC (matrix) converter has been used as the power conditioning core of the power supply, working in conjunction with input and output LC filters. An optimized control system in the ABC frame employing a repetitive controller has been successfully implemented taking into account both the transient and steady state performance targets together with the system effectiveness under extreme unbalanced conditions. Extensive simulations prove the efficiency of the designed system in meeting the international standards requirements.
