But this is for a thesis project, so I assume it is somewhat research related, and he might want to know things to a greater level of detail.? Such as, what is the average voltage over the short time interval when the inductor current is increasing, versus when it is decreasing, or when it is zero.? I don't know the reasons why, but I think it makes sense that he might need to know to that level of detail.
Hello Andy and Tony,
?
What you have mentioned is correct. Accuracy and precision are needed. And I checked the derivative option too. Due to ringing during DCM the derivative makes the situation horrible,
here is a screenshot for your reference. And if you take a closer look, the derivative is maximum around zero crossing just at the start of the inductor current ramp up, when the inductor current is at its peak, the derivative is at an in-between(ish) value (neither maximum, nor minimum). Similarly, during the inductor current ramp down phase the derivative is again at its valley somewhere in between the entire ramp down duration.
You guys really pushed the envelope and thought out of the box to help me solve my problem. I learned a lot from this discussion. I genuinely am grateful to the both of you. However, to solve this particular problem, I'm afraid I can only rely on manually moving the cursor to find specific points then use these points to syntax my .meas statements to keep measurements as honest as possible.
Again thanks to both of you in making me learn new stuff about LTspice.
With Regards,
Ankit
