Figure 13: Input Terminal Ripple Current, i c , at full rated output cur-
rent and nominal input voltage with 10
electrolytic capacitor (100 mA/div). See Figure 12.
Figure 15: Output voltage ripple at nominal input voltage and rated
load current (50 mV/div). Load capacitance: 1
and 15
Figure 17: Load current (50A/div) as a function of time when the con-
verter attempts to turn on into a 1 mΩ short circuit. Top trace
(500µs/div) is an expansion of the on-time portion of the bottom trace.
