Homework Help: Diode Problem

  1. Jun 20, 2012 #1
    1. The problem statement, all variables and given/known data

    What will be the voltage v(t) across diode D1 ?


    2. Relevant equations

    The Figure is shown in the attachment.


    3. The attempt at a solution

    When there is a positive cycle D2 will be open circuit and capacitor 1 will be charged and diode D1 will be short circuited ,while in negative cycle the capacitor 2 will be charged D2 will be short circuited and D1 will be open so all the voltage across Capacitor 2 will be shown against D2 i guess but i am confused with waveform !

    lazy,

    Determine what the diode is doing during every quarter cycle of the wave. Don't forget that capacitors accumulate voltage.

    What i am able to understand is that 1 st half is a clamper circuit and second half is peak rectifier circuit but i am confused about the waveform , for clamping waveform will be shifted to negative axis but what will happen for "peak rectifier" ? what is the exact mechanism of peak rectifier ?

    I am considering each capacitor and diode to be ideal !
