Hi Jeg. Thanks! It sounds like this is the type of circuit I am looking for.
Have you tested this circuit yet? Does it give you a full 0 to 90 degrees phase shift?
If so, I will go ahead and order the parts... :)

Phase shifting degrees, depend on the frequency that you work with. At 17Khz in which i use it, gives much more than 90 degrees shifting. Just change the cap of 3,3nF to a 47nF one (as Itsu had spot it) and you are ready to go. Yes i test it before two days up to the output of 74hc132. Works fine!

ps. It uses an inverting mosfet driver..

Awesome. Are you testing Allega's PWM driver circuit with PLL as well?
I guess that's called the green box circuit? :)

hehe yes the green box! No, I don't use Allega's pll as our beta tester (Itsu) wasn't happy with. Instead he drove it straight out of 494 which made it simpler and easier to use.

Thanks Jeg. That's good to know. I will probably go with the TL494 driver circuit as well.
For now however I will be testing with just the phase shift circuit. Want to run some basic
tests with some simpler setups to see if I can figure out what kicks in the OU. :)

Itsu,

if you disconnect snubbers or/and the 2 tvs (D7, D8) the lag between gate and drain keep the same ?
Usually snubbers are placed across coils and much less sourse-drain of mosfets.   
Try at first disconnecting the 2 tvs and note the difference, and then snubbers.

Hi Sky,

you are probably right, i too think that something in this snubber setup is causing this, i will try to find out by eliminating one by one.
