Title: Bidirectional EMF DC Power Supply
Post by: Lunkster on September 17, 2020, 04:36:33 PM
Bidirectional EMF DC Power Supply

This power supply design is taking the efficiencies that are found in a resonant circuits and using them in a product being in this case a DC power supply.
The resonant circuit creates currents flowing in two directions in the same circuit.  When the output coil of a transformer is in that circuit, the output coil
acts like a driver coil during the times the reverse current occur.  Since flux is created from the currents through these coils, a canceling effect occurs in the transformer that reduces the overall draw in the transformer.
The switching done, on and off in the driver circuit is what causes the changing of direction of current in the circuit.  This switching is done through a Solid state relay that is controlled by a frequency generator circuit.  A LM555 is a good solid state device to create this signal. 
Resonant circuits show great efficiencies, by simulating their performance by controlled circuits can be a big advantage in circuit design.

There are a lot of switching power supply circuits out there.
The old large current power supplies are very heavy because of all the windings in them.
A switching supply is a lot smaller and do not heat up as much as those old supplies.
The reason is because the coils and transformers operating at the lower frequencies
are very inefficient. 
With the switching power supplies, the frequency is increased to reduce the inductance loss at low frequencies.
My motor design would be more efficient if the first transformer was removed so that one transformer operated
with a higher frequency.  THis gets into many of the switching power supply designs.
Now this means many of our devices need to have the designs looked at to reduce operating them at low frequencies
in order to be more efficient.
Now if you took the incoming AC signal and fed that through a switch  in order to produce
a 50hz or 60hz signal that was chopped several times before coming to the
transformer or motor, ect., would the reluctance be less producing a more efficient device?
I thought I ran across a power signal like this somewhere on the internet but can not find it.
But what if someone built a power transformer that had a circuit on top of it to create
a 10K hz chopped 60hz or 50hz power signal to do this?
Would this be a product people would use in the market place?

I seems that when I operate my hand drill and the speed slows down and I get that burning
smell of the coils overheating because of the change in induction, that if the drill
was operated with a chopped power signal, that the drill would slow down without overheating.

I want to know what your thoughts are on this?

After thinking about the power supply for awhile I was wondering how many electronic devices use power supplies.
Even the rechargeable devices have a transformer to recharge them.
So I wanted to take another look at the circuit to see if I could make it simpler and more efficient at the same time.
So I removed one of the transformers because it is another wasteful component to have in the circuit.
So the new circuit only has one transformer.  Now an all solid state circuit would be better than this transformer.

What this circuit is to chop up the 60 HZ going into the transformer into several spikes to reduce the inductive load
in the power supply.  The higher the frequency, the less the inductive load losses will be in a circuit, in my opinion.
That is what this circuit does.  Now this circuit could be used in many applications for the products that we use today.

Have a merry Christmas and a happy new year!
