The invention discloses an airborne airport
wireless communication equipment power supply based on a vehicle-mounted equipment power supply. The airborne airport
wireless communication equipment power supply comprises an input connector, an input filtering and
lightning protection device, an AC-DC module, a DC-DC module, an output filtering device and an output connector which are connected in sequence. The airborne airport
wireless communication equipment power supply is characterized by further comprising a
discrete quantity control module and a slow charge fast
discharge circuit module, wherein the
discrete quantity control module is provided with two input ends and two output ends, the two input ends of the
discrete quantity control module are respectively connected with the output connector and the AC-DC module, and the two output ends are respectively connected with the DC-DC module and the output connector; and the slow charge fast
discharge circuit module is provided with an input and an output end, the input end and the output end of the slow charge fast
discharge circuit module are respectively connected with an output end of the AC-DC module and an input end of the DC-DC module. According to the invention, the vehicle-mounted power supply can be applied to a special power supply for airborne airport wireless communication equipment through introducing the discrete quantity control module and the slow charge fast discharge circuit module.
