Application information
Figure 13. Application schematic
BC
No hard switching occurs at turn-on with BC
MOS Q configuration suppresses the switch-on losses. Added winding, coupled with the
main boost inductor L
both recovery current from the STTH8BC065 and damping current towards the power
circuit. Another added winding in series with STTH8BC065 boost diode discharges the
nominal current stored in inductor L flowing through STTH8BC060 diode towards output
bulk capacitor.
These two added phases compared with conventional continuous mode PFC, bring back
the current corresponding to the usual switching losses in the circuit, hence BC
current circuit).
