    how implement this switching power converter in MATLAB Simulink?

    hi.
    I have to simulate a "Non-Linear Carrier (NLC) Controller" in matlab simulink.
    in one part of my simulation, I have to simulate a "switching power converter" similar to the attachment.
    this converter "gives is(t) current" by using the "c(t) signal as it's driver".
    how implement this "switching power converter" in matlab simulink?
    c(t) (as input signal) and ideal is(t) (as output signal) waveforms are indicated in attachment.

    switching power converter
    Are you describing a switched-coil converter?

    See the thread below. Three basic types are discussed: buck, boost, buck-boost.

    In my posts are links to tutorial simulations. These are interactive and animated, using Falstad's Java applet. (Your computer needs to have Java installed.)

    Re: how implement this switching power converter in MATLAB Simulink?

    I have little knowledge about switching power converters.
    I want to simulate above attachment in matlab simulink.
    How do i have to it?
    Is there anyone who can give me its matlab file?

    Re: how implement this switching power converter in MATLAB Simulink?

    You could either (1) build your own model in simulink by means of existing blocks or (2) model the circuit by means of differential equations (ODE's).
    (1) This would be typically done in the Laplace domain. However, if the power circuit contains many electrical components, this modelling approach becomes tedious.
    (2) In this case the circuit is described as a system of linear equations. The equations depend on the states of the switches and diodes in your model, so the ODE's dynamically change during operation. Again the complexity depends on the number of components in the power circuit. Some commercial tools are available (e.g. SimPowerSystems, Sentrix,...) that apply this approach.
