【Abstract】 In this paper, a kind of power supply of pulse width modulation (PWM), which are used in strong ionization gas discharge, are introduced with the design technique and operational principle of it. Some experiments were operated by using this power supply. The experimental result shows that the power supply meets the demands of dielectric barrier strong ionization discharge, and makes a good application in production of ozone, removal of SO 2 and NOx, and treatment of automobile exhaust.更多还原
