Abstract

The invention discloses an optimization design method for a high-frequency and high-voltage transformer used for electrostatic dust collection. The method comprises the steps of selecting a proper magnetic core; for characteristics of a high-frequency transformer, combining a particle swarm algorithm with a genetic algorithm based on a design method for the high-frequency and high-voltage transformer; and performing optimization design on the transformer by taking a transformer turns ratio and a waveform duty ratio as optimization variables and taking output loss as an optimization target. According to the method, the genetic particle swarm algorithm is adopted, namely, a selection algorithm, a crossover operation and a mutation operation of the genetic algorithm are introduced in the particle swarm algorithm based on the particle swarm algorithm, and the algorithm is simple in iterative process and is advantageous in that the algorithm is easily understood and realized, the convergence speed is relatively high, efficiency is quite high and the like.
