Interleaved PFC Stage
In higher power applications to utilize full capacity power
of mains and reduce harmonics is PFC−regulators generally
required. This high power application use interleaved PFC
stages, where may reduce inductor size, input and output
capacitors ripple current. In overall, power components are
smaller include capacitors. The NCP1632 as voltage mode
IC for interleaved PFC applications used in conduction
critical mode. It drives two mosfets 180
° phase shifted. The
most important at design should be focused significant
inductance value of selected PFC coils. It significantly
specifies working range.
Figure 6 depicts schematic from rectifier input to DC link
output. Activation of stage (connection to 15 V DC power
supply) is via J2 (soldered pads).
