Thanks, woops, my apologies, i accidentally just copied and pasted them in....it should be like in the attached, ie, both boosters fed by the same diode bridge.This is great fallacy often conjured up by newbie engineers - trace all possible return paths for the current and you will see why ...
Can you think of a lower component count way of doing this?
Thanks, ...
Thanks, i am not sure what you mean by "layout"?....as you know, i havent posted any PCB Layouts.BTW your layout is considerably different to the TI one you posted
Thanks, i believe you are referring to the injection of a voltage into the SS pin(?)....i agree......but as explained above it must be done like this otherwise the sim takes till xmas.... please just pretend the master has an output divider in the normal way.still won't work in the real world
AYK, the topology shown is in no doubt, they are 2 PFC Boost converters....paralleledthis has caught out a lot of newbies ... topology is ( often ) everything ...
Thanks, ive just traced it out again (#10 above) with my eyes..the topolgy is boost and is correct for a boost. Whatever is the problem that you are speaking of.....it isnt recognised by the LTspice simulator.the re-drawn ckt has the same topological fault as the 1st ....
the re-drawn ckt has the same topological fault as the 1st ....
