Description

Technical Field

[0001] The present invention relates to the technical field of power electronics, in particular to photovoltaic mobile power supply detection equipment. Background Art

[0002] A power supply detection device is a device used to detect the power supply voltage and realize power conversion and voltage threshold detection.
