成都玛瑞电子设备厂于 1 995年初 ,就对全国ＩＧＢＴ“逆变热”作了冷静的市场调查 ,认为ＩＧＢＴ等新一代逆变型焊机是未来焊机的发展方向。但鉴于当时ＩＧＢＴ作为新一代大功率电力电子器件有待进一步改进和完善 ,工厂没有盲目地一哄而上 ,而是投入较大资金作为科研课题 ,作?
Chengdu Marui electronic equipment factory in early 1995, on the national IGBT “inverter heat” made a calm market survey, that a new generation of inverter IGBT welding machine is the future direction of the development of welding machine. However, considering the IGBT as a new generation of high-power power electronic devices to be further improved and perfected at that time, the factory did not blindly rush into mass production. Instead, it invested a large amount of funds as a research topic for the project.
