一种压接式IGBT组成的多级H桥串联阀段
摘要：
本发明涉及一种压接式IGBT组成的多级H桥串联阀段，包括在一个框架上并列设置的第一组件和第二组件，第一组件和第二组件均为由散热器和IGBT依次交错设置形成的压接式IGBT组件；第一组件与第二组件的对应IGBT之间对应设置有用于导电连接的连接母排，以形成若干串联的H桥，第一组件中的IGBT为所述各H桥的上半区的串联的正向IGBT和反向IGBT；第二组件中的IGBT为所述各H桥的下半区的串联的正向IGBT和反向IGBT。本发明提供了一种由压接式IGBT组成的多级H桥串联阀段的结构，通过合理的布局，组成一个完整的有多级H桥串联的阀段；结构简洁，适于H桥串联。
摘要（英）：

The invention relates to a multi-stage H bridge series connection valve section composed of crimping type IGBTs. The multi-stage H bridge series connection valve section comprises a first assembly and a second assembly which are parallelly arranged on one framework, wherein the first assembly and the second assembly are respectively a crimping type IGBT assembly formed by radiators and IGBTs arranged in a staggered mode, connection busbars for conductive connection are correspondingly arranged among the corresponding IGBTs of the first assembly and the second assembly to form multiple series connection H bridges, the IGBTs of the first assembly are positive IGBTs and reverse IGBTs in series connection of upper half zones of various H bridges, and the IGBTs of the second assembly are positive IGBTs and reverse IGBTs in series connection of lower half zones of various H bridges. Through reasonable layout, the complete multi-stage H bridge series connection valve section has a simple structure and is suitable for H bridge series connection.
