Technical Reference Note
AIF - PFC Power Factor
Correction Series
For example:
A PFC module driving 3 AIF80A300 400W modules @ 5V. Efficiency of the AIF80A300 module is 88%, the minimum
input voltage is 250V, the output voltage of the PFC is 380V, the required hold-up time is 20mS and the peak-to-peak
voltage V
ripple is chosen to be 16V.
C
O min = 2 x (3 x 400/0.88) x 0.02
= 390F (470 F
± 20%)
[(380-16)2-2502]
This figure is the minimum capacitance. To allow for capacitor tolerances and aging effects the actual value should generally
be around 1.5 times greater.
PF & Load Enable Connections and Timing
The PFC module must be supplied with a PF ENABLE signal to initiate the start-up sequence. The output of the LD
ENABLE pin goes HIGH (ON) once the PFC has completed the start-up sequence.
It is recommended that the LD ENABLE signals is always used to enable the load, however, if the load is to be enabled
manually it is essential that the ton time has expired before enabling occurs.
