It should also be noted that the inductance
and the frequency of the “LC” filtering network
should be staggered with the DC/DC frequency
to avoid mutual interference. However, the
capacitance of the output filter capacitor must be
proper. If the capacitance is too big, a startup
problem might arise. For every channel of
output, provided the safe and reliable operation

is ensured, the greatest capacitance of its filter
