Abstract
The small-signal closed-loop input impedance is derived for the PWM buck DC-DC converter operated in continuous conduction mode (CCM), taking into account all parasitic resistances. The plots of the closed-loop input impedance are shown versus frequency for four values of the equivalent series resistance of the capacitor
