摘要
本文介绍了采用电力电子器件IGBT（绝缘栅双极型晶体管）逆变器的电阻焊机．论述了焊机系统的组成、工作原理、开关控制电路及相关的保护装置．所研制的电阻焊机具有高效、节能、体积小。
A resistance-welder which uses the inverter employing the power electronic devices of IGBT is intruduced. The composition of the welder system the prinple of operation,the switching control circuit and relevant protecting devise are discussed Higher efficency, saving energy, lower narmonic pollution and smaller size are the characteristices of the resistance-welder developed.
