摘要
在高压、大功率领域中,绝缘栅双极型晶体管(IGBT)的串联使用备受关注,IGBT的静态和动态均压成为串联使用的关键技术。在研究了多种IGBT串联静态均压和动态均压的基础上,提出一种结构简单、控制容易的均压电路,并对其静态均压和动态均压的工作原理进行了详细叙述。实验结果表明,该电路很好地解决了IGBT在串联使用时的均压问题,在静态和动态过程中,都起到了抑制过电压的作用,能保证开关不同步造成的过电压小于10%,确保了IGBT串联时的有效使用。
The series connection of insulated gate bipolar transistor（IGBT） has been caused more and more attention in the field of high voltage and high power, both static and dynamic voltage balancing of IGBT has become a key technology in series connectlon.Based on studying various static state voltage balancing sub-circuit and dynamic state voltage balancing sub-circuit of IGBT series connection, a simple structure and easy control of voltage balancing sub- circuit is presented and the working principle is described.The experimental results show that the circuit can solve the problems of voltage balancing when the IGBT is used in series connection and have played an important role in inhibition of overvoltage in the static and dynamic process.The overvoltage that caused by switch is not synchronous is less than 10% and the effective use of the IGBT series connection is verified.
