Lame indeed!

I see you got the "poynt".

I think the folks here could benefit from seeing something helpful in your posts. Acting like a smartass does not quite qualify.

Seems odd

the first time i read this post just a bit ago, it read

"  'nul-points = Lame indeed!  "


But no indication that it was edited

In continuation, this might be of interest to a few here.

The configuration is as per 2) above. Gate drive is to Q1, and Q2-Q5 have G and S reversed connections. This is the "as-built" configuration Rose has been testing and posting scope shots on.

Focusing on Vbat and Vcsr as Rose has been, the following scope shots reveal the same negative Vcsr and negative power going back to the battery.

More to follow.

Now the scope shot of MEAN [vbat(t) * vcsr(t)] * 4.

A whopping -192W back to the battery!   

In theory, these two measurements (the -192W and -9.94W) should be the same. Which one do you think is the correct one? Is either the correct one?
