- Abstract
The prospective areas of application of supercapacitors (SC) are resistance spot welding, resistance butt welding as well as pulse-arc welding, where they can be used as slope controllers. Main technical characteristics of SC and bank of SC (BSC), based on series connection of separate SC, are given. Provided are the main calculation relationships, designed for evaluation of electric parameters of BSC, charge-discharge characteristics for developed BSC are experimentally determined. It is shown that the main disadvantage of series connection of SC cells in the bank is a voltage spread, which is proposed to be eliminated in present work by means of application of special charging device - equalizer. Different schemes of equalizers are considered, their advantages and disadvantages when using in pulse current generators are described. Relevance of application of energy-saving scheme of equalizer for pulse welding methods is shown. Scheme of such a device is proposed and described and calculation relationships providing analytical description of its operation are presented. A scheme for resistance spot welding, based on equalizer and bank of 6 SC is given as an example and technical characteristics of the proposed device are presented.
