Figure 9: Test set-up diagram showing measurement points

for Input Terminal Ripple Current and Input Reflected Ripple

Current.

Note: Measured input reflected-ripple current with a

simulated source Inductance (L

TEST

)

of 12 μH. Capacitor Cs

offset possible battery impedance. Measure current as

shown above.
