随着国民经济的发展,冶金、交通、电力等骨干产业,对国产新型大功率电力电子器件,提出了更高的要求。为了适应这一新形势,80年代末90年代初,国产3英寸高压晶闸管的研制,得到了迅速发展。现以全部国产化的冶金部自动化院的新型3英寸高压晶闸管为例,介绍一下其主要特点及应用情况。 (一)新型高压晶闸管的主要特点 新型高压晶闸管主要新在如下几方面: 1.器件的芯片直径为3英寸,单只器件额定电流可达
With the development of the national economy, the backbone industries such as metallurgy, transportation and electric power have put forward higher requirements on the domestic new-type high-power power electronic devices. In order to adapt to this new situation, the late 80s early 90s, domestic 3-inch high-voltage thyristor development has been rapid development. Are all the localization of the Ministry of Metallurgy Automation Institute of new 3-inch high-voltage thyristor, for example, introduce its main features and applications. (A) the main features of the new high-voltage thyristor The new high-voltage thyristor mainly in the following aspects: 1. Device chip diameter of 3 inches, a single device rated current up
