Description
technical field [0001] The invention relates to the field of supercapacitor circuits, in particular to a test system for supercapacitor circuits. Background technique [0002] With the operation of various power terminal equipment in the power grid, this puts forward new requirements for the operation standard of power terminal equipment, that is, in the case of power failure, the super capacitor circuit in the power terminal equipment needs to be able to support the operation of the power terminal equipment. Provide power for at least 3 minutes to ensure that the power terminal equipment completes the necessary execution operations. [0003] In order to meet the discharge time requirements of power terminal equipment for its built-in supercapacitor circuit, it is necessary to accurately test the charging and discharging circuit of the supercapacitor and the step-up and step-down circuit to ensure that problems can be exposed before the production of power terminal equipment...
