Abstract

A DC power supply charger of an unmanned aerial vehicle (UAM) communication device comprises a charging power supply, a charged power supply and charging reference voltage and also comprises a primary charging module and a secondary charging module, wherein output ends of the primary charging module and the secondary charging module are separately connected with a first capacitor and a second capacitor, the other ends of the first capacitor and the second capacitor are grounded, the primary charging module is used for charging the voltage of the first capacitor to a voltage value of the charging reference voltage, and the secondary charging module is used for charging the voltage of the second capacitor to a voltage value of the charging power supply; and the DC power supply charger also comprises a voltage division circuit and a load open-circuit protection module, the voltage division circuit outputs the charging reference voltage, and the load open-circuit protection module is connected between the charged power supply and the ground. By the DC power supply charger, the ripple noise of the power supply during charging is reduced, the data loading density can be improved, the communication data transmission efficiency is improved, and meanwhile, the DC power supply charger has functions of open-circuit detection and protection.

Description

technical field [0001] The invention belongs to the field of electronic communication, and relates to a communication charging device, in particular to a DC power charger for a drone-borne communication device. Background technique [0002] In various electronic devices, different modules usually require different DC power sources, and usually one DC power source charges other power sources to obtain DC power sources with different potentials. For communication equipment, with the reduction of power consumption and signal voltage amplitude, the noise signal tolerance of the system is getting smaller and smaller, especially when power supply noise is superimposed on the signal, the impact on signal distortion is reflected with the reduction of power supply voltage an increasingly pronounced impact. In the communication equipment carried by drones, since the power supply itself is converted from mechanical energy, the power supply itself has strong ripples. When the communica...
