Aiming at the problem of the abnormal load state of the pulse electrostatic precipitator and the modeling of the pulse high frequency dust removal power system is difficult

this paper presents a characteristic control method for the pulse power supply for electrostatic precipitation. By means of characteristic modeling algorithm

combine with the performance index and error class characteristic of pulse power supply for electrostatic precipitation

to achieve control output of characteristic control method

further

the driving frequency of the inverter circuit and the pulse generating circuit is obtained

and precise control of the output voltage and the pulse number of the pulse dust removing power source is realized. In the simulation experiment

the system structure of pulse power supply for electrostatic precipitation based on characteristic model algorithm is built by SIMULINK.the simulation results are compared with the proportional-integral-differential（ PID） method

which has the advantages of fast rising time

short stable time and small steady-state error.
