Abstract

To extent 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 got to balance by adding a RCD snubber and an adequate balancing resistor in each IGBT in series. For parallel method, a parallel scheme using current feedback method is proposed in this paper. The above serial and parallel techniques are proved that the currents of paralleled IGBTs and the voltages of IGBTs in series can be balanced by experiments.
