Problems solved by technology

Conventional resistance boxes and electronic loads can no longer meet the requirements
The main reason is that the switching speed of the mechanical switch of the resistance box is slow, and the contacts are sintered under high-frequency current, while the response speed of the traditional electronic load is slow, about 2.5A / uS, without pulse function, which cannot meet the current requirements of this item. 600A / uS current response speed and 150nS load switching speed requirements

Abstract

The invention discloses an overspeed electronic load system. The overspeed electronic load system comprises a man-machine interaction interface, a control system, a resistance matching module, a sampling circuit and an output port, wherein the resistance matching module comprises the resistance network and electronic switches, a resistance value is divided by the resistance matching module into different multiple value segments, each resistance value segment internally comprises multiple different resistance values and the electronic switches in parallel and series connection modes to carry out resistance value matching to form the resistance network, an output end of each resistance value segment outputs a resistance value through a relay switch to an output port of an electronic load, the man-machine interaction interface and the control system are connected and realize mutual data transmission, and an output end of the control system is connected with the resistance matching module and is used for controlling resistance matching of the resistance matching module.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to an electronic load system. Background technique [0002] The load is the necessary equipment for power detection, which is used to detect the load capacity, response time, power quality and other indicators of the power supply. In applications with low requirements, a resistance box composed of passive components and mechanical switches is used as the load, which has simple functions and low price. In high-precision applications, most of the electronic loads are used as the detection load of the power supply. The electronic load has the characteristics of high precision, continuously adjustable load current or voltage, and complete functions. The relative price is relatively high, and the response time is generally in milliseconds. Performance test for DC power supply and power supply below intermediate frequency. [0003] For the current special power supply, such as...
