Abstract

Most conducted EMI prediction for switching mode power supply adopts time domain simulation, the transient process establishing the output voltage takes large part of the simulation time. The appropriate control parameters can reduce the system overshoot and adjustment time, thus shorten the simulation time. Take the flyback converter as the research object, the genetic algorithm (GA) with global optimization advantage is used to optimize the classical PID control parameters. The simulation results show that the optimized PID control has lower overshoot and adjustment time than the traditional PID control, shortens the simulation time effectively while maintaining the accuracy of conducted EMI prediction.
