Given that the above is the instantaneous source current drawn by a buck converter, may I know how I should go about determining the corresponding average value of the source voltage?
Here's what I have attempted or understand could lead to a solution.
1) The gradient of the positive slope in the current waveform equals to the source voltage over inductance value. However, the inductance value is not given.
2) I could calculate the duty cycle of the converter using the on and off period. And possibly find source voltage if I have the output voltage but the output voltage is not given either.
