Transformer primary secondary inductance values

[okbro]

I am simulating an inverter that uses a 12-0-12V transformer as shown. In my simulation part i need to enter the inductance values for primary and secondary winding. Does anyone know the typical value for the inductances? Thanks.

Not a good schematic.

Looking at the datasheet for the CD4047, I think it is a very poor choice as a PWM controller in a push-pull circuit.

• The two complimentary outputs are truly complimentary, which means one of the two is always on. The timing for a proper push-pull drive needs some dead time, which is a period when neither output is on. Without any deadtime, there will be a period of time at each transition when both mosfets will be on. This creates brief short circuit conditions which use battery power but produce no output power. This is known as shoot through.
• The output current from the two outputs is only a few mA, so the turnon and turnoff times of the mosfets will be farily long, which means they will spend a good portion of the time in their linear conduction mode. This makes the shoot through period much longer, wasting more power.
