    Hi,

    I'm very new to LTSpice and am trying to implement an output voltage regulated Buck converter through the use of the 'bv' behavioral voltage source.

    The converter is being driven by a PWM generated waveform which I have generated using a triangle wave (using the PULSE option of the voltage source) and am using a bv source in the main circuit to test this against a threshold value to feed an ideal switch. I'm now stuck as to how I go about modifying the duty factor for the switching voltage to maintain a constant output of 10V, using another bv source?

    Any ideas?

    Regards,

    J.
