Figure 13: Input Terminal Ripple Current, ic, at full rated output cur-
rent and nominal input voltage with 10 H source impedance and 47 F
electrolytic capacitor (100 mA/div). See Figure 12.
Figure 14: Input reflected ripple current, is, through a 10 H source
inductor at nominal input voltage and rated load current (5 mA/div).
See Figure 12.
