Problems solved by technology

[0003] At present, the energy-saving and emission-reducing new energy power supply system technical scheme implemented for the communication base station AC and DC power supply system mainly uses wind energy generators as the original power supply system to supplement new energy power, and the DC voltage output by the fan controller is directly connected to the communication base station. The rectifier output DC bus in the power supply system is connected in parallel, and the mains power supply is still the main power supply, which does not achieve the purpose of fully utilizing new energy
On the other hand, if the wind energy engine supplies power to the communication equipment and at the same time charges the storage battery, the power of the wind energy engine needs to be increased, resulting in high investment costs and low utilization.
