摘要
Abstract
In response to the characteristics of the low overall circuit inductance for the new energy vehicles using batteries as their power source,a low inductance DC testing system is developed using the supercapacitor modules as experimental adjustable power sources,IGBT series connection and synchronous drive,non-inductive resistance,PLC control,and other technologies.The system has a maximum short-circuit detection capacity of 20 kA/DC 1 500 V and can be used for various tests of new energy vehicle electrical appliances(such as DC contactors,fuses,etc.)under low inductance(time constant of 0.5ms and below)conditions.At the same time,the problem of high inherent inductance caused by long transformers and transmission lines in the DC testing system using rectification form,which can not meet the requirements of low inductance testing,has been solved.关键词
