In order to solve the shortcomings of traditional wind fire extinguishers such as bulky structure, ionic-wind-based fire extinguisher power driver system is modeled and designed. The overall structure is designed, and the rationality of its internal circuit topology is simulated and experimentally verified. A closed-loop system is proposed to control the wind power by adjusting the DC voltage, and the theoretical model is derived and verified. The power drive system allows the wind fire extinguisher to produce high speed ionic wind for fire extinguishing, with a lightweight structure and green energy saving.
