State-space average Modeling of DC-DC Converters ... - CORE
core.ac.ukDiscontinuous Conduction Mode occurs due to low load current operation of converters which employ current or voltage unidirectional switches. The switching ripples in inductor current or capacitor voltage causes the polarity to reverse of the applied switch current or voltage and thus a zero current mode is reached.
