Plug-In Hybrid Electric Vehicle Battery Chargers Using a Single Phase PFC Converter
The authors introduce an ac–dc front-end power factor correction solution for PHEV battery charging operations. The system design enables accurate dc output delivery and minimizes harmonic content in the ac input and improves power quality through power factor regulation. The research introduces a boost converter topology which operates in continuous conduction mode to minimize significantly input current harmonics. The system achieves digital power factor correction by implementing control functions through an inexpensive digital signal controller. The research continues with theoretical and experimental implementation of the suggested converter and its control methodology through digital control system development. A detailed approach for converter operation and universal ac input voltage control from 150–340V to produce 480V dc output at 5.0 kW load is described using both theoretical and experimental measurement data with a power factor surpassing 0.84. Experimental findings show that the new control approach provides plug-in hybrid electric vehicle (PHEV) battery charging applications with both advantageous features and operational flexibility.
