ABSTRACT:
An airplane ground support system includes a multi-voltage power supply. This system includes an air conditioning module and a control module having a display and a processor, the display and processor presenting an airplane type or class selection menu to airplane support technicians and responding to the selection of a type or class of airplane by generating a power output selection signal designating the type of power needed by the selected type or class of airplane. The system also includes a power supply module which has an A.C. power input, at least one power output, and which receives the power output selection signal as an incoming signal. A power conversion system within the power supply module connects to the A.C. power input and supplies converted and voltage regulated power to the at least one power output. This power conversion system also receives the power conversion control signal as an input signal. A control system within the power conversion module receives measurements of the voltage at the power supply module's at least one power output and also receives the control module's power output selection signal. This control system generates the power conversion system's power conversion control signal and adjusts it to regulate the power module's output to a predetermined preset voltage level as mandated by the power output selection signal.
