Multi-voltage power supply for aircraft cart-type universal ground support equipment.

摘要

The aircraft ground support system is equipped with a multi-voltage power supply. The system includes an air conditioning module, a control module, and a power supply module. The power supply module has an AC power input and at least one power output, and has a power output selection signal as an input signal. A control system in the power conversion module receives a measurement of the voltage at the power output. The control system generates a power conversion control signal and adjusts the power conversion control signal to manage the power module output to a preset voltage level specified by the power output selection signal. In an alternative embodiment, the multi-voltage or upgradeable power supply has AC and DC functions, and if it is an AC only function, it has an upgrade function that can be used to add a DC function in addition to the AC function. However, in the case of a DC-only function, it has an upgrade function that can be used to add an AC function in addition to the DC function. The power module has an AC power input and at least one power output, and when the AC function and DC function are installed, receives a power output selection signal as an input signal or by selection from an operator .
