Abstract :In this study, the design guideline for the power stage of true-bridgeless AC-DC power factor corrector (PFC) converter is provided, and working principle is explained. The dynamic responses, total harmonic distortion and power factor of true-bridgeless PFC converter are analyzed using predictive current control with pulse train strategy techniques and average current mode control for different load conditions. The main mathematical framework of the control algorithm is introduced, simulation and control charts are presented. The simulations are performed to illustrate the advantages of the method and compare it with average current mode control approach. According to the simulation results, input current complies with the IEC61000-3-2 Standards. In the control of the converter using the predictive current control with the pulse train strategy, it is observed that dynamic response of the converter is improved compared to average current control method.
