This research proposes a study on operating modes, control technique, design, and simulation of the bridgeless totem-pole power factor correction (PFC). This PFC has high efficiency and the advantage of the totem-pole circuit where two high-frequency switches for boosting and two diodes for conducting current at line frequency. This results in the loss of the diode's reverse recovery current has been reduced. As this advantage, this research will focus on the study of operating modes and control techniques of bridgeless totem-pole PFC, where this PFC has been modeled and simulated. This model will be adopted for prototype designs and used as one component in various modern power electronics systems simulations. To confirm the validity of the study, three types of PFCs including boost, bridgeless, and bridgeless totem-pole have been simulated for discussion of current and voltage waveform and comparing the efficiency and total harmonic distortion. The simulation results show the model and control technique presented in this research can be worked very well and the bridgeless totem-pole PFC has the highest efficiency.
