Abstract：High power semiconductor switch reversly switched-on dynistor(RSD) is one of the semiconductor devices with the largest conductive current capability, and features high d#em/em#/dt and low power dissipation. Trigger parameters are main factors which have considerable impact on conducting state of RSD. Influence of different amplitudes and pulse widths of trigger current on conducting state is investigated by experiments. Curves of peak switching voltage of RSD as a function of trigger charge with four different pulse widths of trigger current, 2μs, 1μs, 500ns and 250ns are obtained, and cause of ununiform switching under 250ns pulse width is discussed. It’s shown that proportion factor in critical trigger charge equation increases with trigger pulse width increment.
