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 WebKeep in mind the optimal ripple current of the inductor should be about 40% of the output current. This is a good rule of thumb for most dc/dc converters and represents a trade-off between small inductor size and low switching losses. For a …
