Solid State Amplidyne Idea

[Neo-X]

Hellow 2 all.. I have an idea of ou transformer based from amplidyne, thane heins and ismael aviso. In the picture below you will see that it is quite similar to thane heins bi-torroid except that the third coil was omited. The operation was simple. When 60hz ac voltage was supplied to the primary coil, a voltage will induce to the secondary coil. If the IGBT is open, the secondary coil will become short circuited and a large magnetic flux would build-up in the second coil. This magnetic flux will flow on the right side magnetic path. An airgap was added so that the primary coil magnetic flux cannot go to the right side magnetic path. When the IGBT suddenly closed, a large BEMF from the secondary coil will flow to the load. This process should repeat many times to produce more power. IGBT should be supplied by a pulse signal in frequency raging from ten to hundred of kilo hertz. Thats all.. Feel free to comment and i greatly appreciate it..

Thane Heins Bi-Torroid and Aviso shorting module circuit

Hi, the coil shorting module you provided is mine As far as I am aware Avisio hasn't provided any circuit schematic so I came up witch this... (not tested yet!)

When 60hz ac voltage is supplied to the primary coil, a voltage will be induced in the secondary coil.

Yes, because the magnetic flux flowing through the center leg winding is changing.

If the IGBT is open, the secondary coil will become short circuited

No, an "open" IGBT has infinite resistance and does not conduct electric current. When the IGBT is open, then the center leg winding is open-circuited and electric current cannot flow through it.
In russian language an "open" switch has zero resistance, but not in english.

and a large magnetic flux would build-up in the second coil.

If the center leg winding is closed then the current in this winding will oppose any flux changes in the center leg. It will not create any additional flux in the center leg.

This magnetic flux will flow on the right side magnetic path.

Does "this magnetic flux" mean the magnetic flux produced by the winding wound over the left leg?
If "yes"  then this flux will flow in all legs according to Hopkinson's Law, when the winding on the center leg is opened (not short-circuited).
This flux will flow only in the left and right leg, if the winding on the center leg was short-circuited (closed), when the flux in the center leg was zero (e.g.: before any flux was generated in the left leg).

An airgap was added so that the primary coil magnetic flux cannot go to the right side magnetic path.

An air gap does not prevent the magnetic flux from flowing through it. It just decreases the flux by presenting more reluctance to it, according to the Hopkinson's Law.
