In order to study switching impulse generation and generator compact, easy to move and use on site, a new method is proposed, which could generate switching impulse with IGBT triggering control and transformer electromagnetic induction, and then the switching impulse generator is developed. Compared with traditional switching impulse generation method based on Marx with traditional spark gap, IGBT can accurately control impulse voltage trigger without strong electromagnetic interference, generator size is remarkably reduced by using transformer electromagnetic induction to boost impulse's amplitude, and the efficiency of changing waveform is improved by adjusting primary side circuit parameters to generate different double exponential and oscillating switching impulse respectively. Experimental results show that generated switching impulse has advantages of high output efficiency, stable output and small waveform distortion. Besides, this generator eliminates strong electromagnetic interference and noise caused by sphere gap breakdown. Therefore, it can be applied to impulse voltage withstand test well on site and has good application prospect.
