Equipment for supplying hybrid power by utilizing solar energy based on multi-phase alternating method

Abstract

The invention discloses equipment for supplying the hybrid power by utilizing the solar energy based on a multi-phase alternating method. The equipment comprises a solar power generation part, a storage battery part, a power supply circuit and a power supply control part. The solar power generation part is used for generating power by utilizing the solar energy. The storage battery part is used for storing and providing the current. The power supply circuit is electrically connected with the solar power generation part and the storage battery part and comprises a load end used for consuming the electric power, and a power supply end used for generating power for daily use. The power supply control part is used for controlling a power supply and a loop and providing the current from the solar power generation part to the storage battery part / the load end / the power supply end, or from the power supply end to the storage battery part / the load end. The power supply circuit part is designedto charge / discharge the storage battery part through the multi-phase alternating method, so that the voltage is reduced or increased. According to the invention, based on the application of the multi-phase alternating method, the demand of the maximum power is reduced in the charging / discharging process of the storage battery part.

Description

technical field [0001] The invention relates to a device for providing hybrid power in the field of power supply, in particular to a device for providing hybrid power through solar energy by applying a multi-phase interleaving method.
