Power Factor Correction design for On-Board Chargers in

Brian Johnson ABSTRACT This application note discusses the design comparison of a Continuous Conduction Mode (CCM) Power Factor Controller (PFC) versus a two-phase interleaving CCM PFC for on-board chargers in electric vehicles An on-board charger (OBC) is generally a two-stage design with a boost topology power factor

What does PFC stand for?

What is the efficiency of a PFC circuit?
Again the efficiency keeps high in a large power range. More specifically, it remains higher than 91% for input powers ranging from 67 to 330 W. In standby (no load conditions), the PFC stage enters a stable burst mode, where the circuit keeps regulating the output voltage and minimizes the power consumption.
What type of PFC is used for a power supply?
Medium and large power supplies with a capacity greater than 500 W are now widely used. In principle, a multi- phase interleaved PFC may be used for such power supplies, but a large majority of them use a two-phase interleaved PFC circuit like the one shown in Figure 3.2.
What is a PFC preconverter?
It was specifically created to answer power supply designers' growing concerns with satisfying government issued energy regulations. The latest trend of regulations, such as IEC1000-3-2 requires the use of PFC preconverter in power supplies with power ratings of 75 W or higher.
