Abstract :
Expressions are derived for the small-signal closed-loop input impedance of the PWM boost DC-DC power converter using an existing small-signal model for continuous conduction mode (CCM). All parasitic components are included in the model. The plots of the closed-loop input impedance including the real and the imaginary components are shown versus frequency for three values of duty cycle
