Figure 17: Input Terminal Ripple Current, ic, at full rated output cur-
rent and nominal input voltage with 4.7 H source inductor and 100 F
electrolytic capacitor (100 mA/div). See Figure 16
Figure 18: Input reflected ripple current, is, through a 4.7 H source
inductor at nominal input voltage and rated load current (10 mA/div).
(See Figure 16)
Figure 15: Output voltage response to step-change in input voltage
(1000V/ms). Load cap: 200 F, electrolytic output capacitance. Ch 1: Vin
(20V/div), Ch 2: Vout (500mV/div).
