WebFlyback topologies are practical and lowest cost for systems up to power levels of 100W. Above this power level other methods such as forward converters become more cost effective, due to reduced voltage and current stresses on the devices. Flyback transformer design is a somewhat iterative process, due to the number of variables involved, but it WebA forward converter also usually requires an additional inductor L1 on the output side. However, through this, the output voltage can also have a lower ripple than that of a flyback converter at the same power level. Power management ICs such as the ADP1074 from Analog Devices offer a very compact solution for designing a forward converter.
