| | Control of static frequency chargers for aircraft ground power supplies with stringent performance requirements
By P. Zanchetta; J. Clare; P. Wheeler | |

Abstract: This paper describes the design philosophy, simulation and testing of a 40kVA ground power supply
unit (GPU) for aircraft servicing. Instead of the classical design using a diode bridge rectifier, a DC
link and a PWM inverter, a 3-phase to 3-phase direct AC-AC (matrix) converter has been used as the
power conditioning core of the GPU. An optimizing control design method, using a genetic algorithm
approach, has been used which yields designs to minimize a cost function taking into account both the
transient and steady state performance targets. Extensive simulations prove the efficiency of the
designed system in meeting the international standards requirements.
