Partnered Output Coils - Free Energy

So in testing some !off the shelf! transformers,i have found that it is the winding configuration that sets the primary and secondaries current phases.

The first scope shot is with one winding configuration between primary and secondary coils. As you can see,the secondaries current leads that of the primaries current. In the second scope shot where the winding configuration is different(but on the same type of core),you can see that the primaries and secondaries current are in phase. Same resistors used in both test.

Soo.  If the core is not of the highest permeability type, then what?

I am not in agreeance on this one Brad.

It is the Load that determines the Phase Shift for "!off the shelf!" Transformers.

A Resistive Load - should always be zero Degrees or close to it.
An Inductive Load - Should be a Current Lag.
A Capacitive Load - Should be a Voltage Lag.

This should be true on most all circuits/Transformers but not all. Some resistors (Wire Wound mostly) can have Inductive (XL) and Capacitive (XC) Components to them. This is mostly a High Frequency thing and very rarely seen to be a major problem at low frequencies.

Could you elaborate?

A Transformer Core is selected for a particular operating range.

For example, we want to Transform 240volts 50Hz Mains to 12 Volts but only need max of 3 amps...

We need a very small transformer because it's got to fit inside a very small box.

Max height is 3cm's, we need a Cross Sectional Area of 1 Sqcm, and we need the coil to fit in a 2cm former, 32 turns, so we need a Permeability of 5000 for a Magnetic Field Strength of 60.31 Gauss.

As a safety precaution we might want to go up to 6000 for the permeability so as we have a safe operating range.

The calculations for this can be found online, many good websites about transformer theory can provide calculators that can estimate these parameters.

P.S: If the Core is not satisfactory, leaking the Magnetic Flux then all sorts of things could happen, firstly and most importantly the transformer will not operate within its parameters.  Remembering that Air is very much harder for Flux to traverse than High Permeability Material, the last thing the Flux will want to do is exit the Core.

A Saturated Transformer can be rather dangerous, Current can go through the roof and this can happen:
