Title:
SELF-COMPENSATING PHOTOELECTRIC MAINS AUTOMATIC COMPENSATION SYSTEM AND DEVICE, AND METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/005132
Kind Code:
A1
Abstract:
The present application relates to the technical field of photovoltaic power supply, and in particular, to a self-compensating photoelectric mains automatic compensation system. The system comprises: a photoelectric access module, a photoelectric boost module, a mains access module, a mains rectification module, a sensing conversion module, a comparison module, a mains compensation module, a dual-power drive module, and a power supply output module. In the present application, the mains access module connected to the mains is provided, the mains is used as photovoltaic supplementary electric energy, and when there is fluctuation in power of the photovoltaic electric energy, the output power can be stabilized by supplementing the mains. There is no need to additionally provide a storage battery and an inverter for stabilizing output, the space occupied by an apparatus is released, the purchase cost is reduced, and the photovoltaic power supply is convenient to popularize in a large range. Also disclosed are a self-compensating photoelectric mains automatic compensation device, and a self-compensating photoelectric mains automatic compensation method.
