In C-Dump converter, imagine that Tl switch is turned
on to magnetize the phase A. While the phase current
exceeds the reference value, Tl switch is turned off,
this allows the Dl diode to be forward biased and Fast
demagnetization is achieved by, increases the voltage
across Dump Capacitor by closing the current path and
then the excess voltage from the (dump) capacitor is
given into the power supply[ 12],[ 13].
