The conventional methods such as selective catalytic reduction method, electron beam method and lime gypsum method could not treat exhaust gases completely. In addition, the energy efficiency and the cost of the conventional ways are still unfavourable. In recent years, the pollution control techniques using electric discharge plasmas which attract attention as the low cost and high energy efficient exhaust gas treatment methods, have been widely studied. In our laboratory, pulsed streamer discharge plasmas which are one of the non thermal plasmas have been used to treat exhaust gases. Since a pulse width of applied voltage has a strong influence on the energy efficiency of the removal of pollutants, the development of a short pulse generator is of paramount importance for practical applications. In this work, nanosecond pulse generator which can output the 5 ns pulsed voltage is developed. In addition, the exhaust gas treatment and the ozone production by nanosecond pulse generator were demonstrated.
