为了扩大IGBT的额定电流和额定电压范围，本文提出了串联和并联的方法。对于串联技术，发现可以通过在串联的每个IGBT中添加RCD缓冲器和适当的平衡电阻来平衡电压共享。对于并联方法，本文提出了一种采用电流反馈法的并联方案。通过实验证明，上述串、并联技术可以平衡并联IGBT的电流和串联IGBT的电压。
To extend the rating ranges of current and voltage of IGBT, the serial and parallel methods are presented in this paper. For serial techniques, it is found that the voltage sharing can be made to balance by adding an RCD snubber and an adequate balancing resistor in each IGBT in series. For the parallel method, a parallel scheme using a current feedback method is proposed in this paper. The above serial and parallel techniques prove that the currents of paralleled IGBTs and the voltages of IGBTs in series can be balanced by experiments.
