As the key of electrical part in electrostatic precipitator （ESP）, High-voltage power has important effect to improve collection efficiency and reduce power consumption. This paper proposes a design method of a new pulsed high-voltage power for ESP, which consists of superposition of DC and high-voltage pulse. Then, this paper studies the modeling and analysis of the high-voltage pulse circuits, and obtains design parameters by theoretical analysis formula. Finally, the experimental results of the new pulsed high-voltage power system gaining by MAT-LAB/SIMULINK simulation, and the comparison with parameters of actual pulse transformer product shows this design method is effective and feasible, and has a certain guiding significance to the actual product development.
