    How to get to this instantaneous power equation?

    Hi everybody As you can see, [1] are voltage and current with their respective phase angle. [2] is the instantaneous power, which I could solve from [1] But my question is: How can I get [3], if I read the next: instantaneous power is given by [3] where the voltage is resolved onto in phase and...

    help with thyristor rectifier in Matlab/Simulink/Simpowersys

    Hi everybody, recently I tried to simulate a rectification using thyristors as the figure 1, in figure 2 signales from ac voltage in and dc voltage out, figure 3 the pulses. Your help: in third page, why isn't there a recification, I mean there is a pulse with out consequences
