Not having a go at you. Possibly/Probably your Tutor/Lecturer..
Perhaps Mary Gannon from TI Ireland can help you out with that question. Obviously not interested.
Elsewhere,

This might, or will, be Lloyd Dixon from Unitrode, as was before they...
Perhaps Mary Gannon from TI Ireland or Harwin with their new ACE award can join in on the discussion. Ooops did not think so. Why am I receiving their totally unrelated marketing spam?
Morning. Back again. Returning to,

It's a bit difficult to separate out which bobbin is which but using minimum figures the available winding width, Ww, is C 26mm. The available winding height is (A-B)/2 or about 5.8mm.
We'll assume you are going to use 3mm margins...
It is later. Shopping done. Let's do sums.
Bear in mind that this is a methodology and you can vary it according to your own requirements and goals. I'm going to base this on convection cooling whereas the 'headline' figure suggests the manufacturers have chosen to give a figure for forced air...
Yes.. A half-bridge suffers from the opposite problem. Unless you include flux-balancing windings of take other actions then when trying to use current mode control the 'soft' capacitor centre return is subject to drift. With voltage mode control that drift acts to compensate against flux...

Jameco give "Manufacturer no. PC40HEER35-Z" PC40 is a TDK core material and EER35 looks like the core shape.
Unfortunately it looks like the product has been deprecated by TDK so best guess would be Jameco are...
Let's do the voltage mode control 'deal breaker'.
In as much as the primary magnetising inductance gets set during switch on time it has to be reset during switch off time. In the case off your push-pull converter one switch drives it one way and then the other switch drives it the other way...
That's one of the suggested advantages. More importantly current mode control, peak or average, avoids flux walking in the transformer's primary magnetising inductance preventing saturation.
This is a problem in voltage mode control for both push-pull and full-bridge converters and it has been...
Yes.. Your output voltage is higher but that's because of the transformer. Topologically it is still a Buck configuration. If you were to normalise what is on the secondary back to the primary you would find that the 'output' voltage is in fact less than the input voltage.
If I remember...
Would you consider doing something 'completely different', that is likely to involve more pain and will similarly be doomed to failure?
At the moment you are using a push-pull converter to generate a DC output bus for your full bridge and then using PWM, via a micro-controller, to gain some...
