Title:
LOW-COST SUPERCAPACITOR CHARGING CIRCUIT SUITABLE FOR SINGLE-PHASE ELECTRICITY METER
Document Type and Number:
WIPO Patent Application WO/2023/065416
Kind Code:
A1
Abstract:
The present invention relates to a low-cost supercapacitor charging circuit and system suitable for a single-phase electricity meter. The charging circuit is used for charging a supercapacitor, and the voltage output from a charging voltage output end is adjusted by means of an output voltage adjustment module connected between a charging voltage input end and the charging voltage output end, such that the voltage at two ends of a supercapacitor to be charged is reduced, and the overall life service index of a single-phase intelligent electricity meter is improved. According to the technical solution provided in the present invention, the current consumed by the charging circuit per se is relatively low, the circuit working state of the charging circuit is stable, the device structure is simple, and the cost is low.
