... From an oscillator standpoint, the switching cycle con- sists of only an on-time and an off-time. But from an February, 1997 Toko, Inc. inductor current standpoint, the switching cycle breaks down into three important sections: on-time, off-time, and deadtime. The on-time of the switch and the inductor current are synonymous ...
