Among the available topologies, a boost circuit
operating in continuous current mode is the only
topology which enables the RFI noise across the
input capacitor to be limited, and consequently a
lower cost filter is required. Also, the boost inductor
stores only a part of the transferred energy,
because the mains still supplies energy during the
demagnetization phase of the boost inductor - so
the magnetic part required is smaller than needed
with any other topology. Therefore the boost topology
leads to the cheapest solution.
