A High Range Buck-Boost PFC Converter for Universal Input EV Applications
In this paper, a buck-boost PFC AC-DC converter is suggested for on-board electric vehicle charging (OBC). This converter can be utilised as a part of an OBC system at the front-end for low voltage (LV) battery charging with ratings ranging from 1kW to 3.3kW. In traditional buck-boost with high gain at roughly unity duty ratio, inductor is shorted to source, causing capacitor discharge to load. But with the use of two MOSFETs and two diodes as per the proposed configuration the above mentioned issue can be eliminated with out increasing the additional device count.Moreover, a positive voltage at the output can also be obtained with increased voltage range. Simulation findings are presented to support the viability. The converter can operate with a wide input voltage range of $\mathbf{60}-\mathbf{270}V$ AC while maintaining input current THD within limits.
