Bidirectional EMF DC Power Supply

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.
