Abstract: In order to resolve the shortcomings of traditional single L-filter dynamic performance, LCL filter is introduced to PWM rectifier, which has a smaller inductance value and a good filtering effect. A new method PWM rectifier based on LCL filter parameter optimisation is proposed in this paper. A mathematical model of the PWM rectifier with LCL filter is built. The particle swarm algorithm optimisation programme is designed by MATLAB. This method can find the global optimum through following the searched current optimal value and is relatively simple compared to traditional distribution design method The experimental results show that this method has better performance and the convergence of particle swarm optimisation.
