Detection of capacitive mode operation via C18:
The DC level at pin RES is set by R36 and the source current I
∆V
Selected value: C18= 82pF.
Bandpass filters L21/C21 and L22/C22 can be used in order to conduct filament currents preferred at preheating
frequency and to suppress these currents during run mode.
Inductor L1 of the boost converter:
The inductivity of the boost inductor typically is designed to operate within a specified voltage range above a
minimum frequency in order to get an easier RFI suppression. It is well known, that in critical conduction mode
(CritCM) there is a minimum operating frequency at low input voltages and another minimum at maximum input
voltage. In state-of-the-art CritCM PFC controllers we use the lowest value out of these two criterias:
At minimum AC input voltage:
At maximum AC input voltage
With the new control principle for the PFC preconverter we have a third criteria that covers the maximum on-time
t
With the assumed conditions the lowest value out of L
Selected value: L1= 1,58mH.
