Hi Johny,

Please give me a day or two to look at this issue, I need to install PSPICE on my machine first.

Hello Johny

I've been able to get the sim running. Your traces stop at 2ms but I don't see anything happening in the sim until about 10ms at which point the FB signal increases and the SS ramp starts. I'll let the sim run overnight here and let you know what happened

Regards

Colin

Hello Johny

I let the sim run out to 130ms with the result below.

Here's an expanded view at around 130ms

Let us know how you get on - and let me know if the images don't appear

Regards

Colin
