The voltage stress across all the active switches is half of the
input voltage before turn-on or after turn-off when the operating
duty is below 50%, the capacitive discharging and switching losses
can be reduced considerably. It has a higher step-down conversion ratio
and a smaller output current ripple compared with a conventional
IBC. (Ref:IEEE Paper -Interleaved Buck Converter Having Low Switching
Losses and Improved Step-Down Conversion Ratio)
