基于PSO实现的三相高功率因数PWM整流

onventional rectifier link generally adopts the diode rectifier circuit, when the system is running a large amount of harmonic is injected to the power grid, the power factor is low. Due to the PWM rectifier can realize grid-side current sinusoidal, and run on unit power factor, even can realize energy bidirectional transmission, it has truly achieved the "green electricity transformation", thus it made more extensive application in related fields. In this paper, based on the elaboration of PWM rectifier working principle, the SVPWM voltage type control strategy is adopted to improve the utilization rate of network voltage, a method based on particle swarm optimization algorithm is using to realize self-tuning of PID control parameters, the method has improved the control performance of the PWM rectifier controller.
