The proposal describes tapping an unknown energy-source, told to operate years ago, but not yet reproduced. The principle is unexplained. The setup came from Prof. S. Marinov of Sofia University via a colleague at Vienna University. A setup has been confirmed by the TÜV-München.
In 1989-91 the colleague reported about investigations on a special transformator consisting of magnets and coils.
The hysteresis loop was passed by applying a pulsed current to the primary coil. Surprisingly, the secondary coil was said to produce more electric power than the primary coil needed, depending on the pulse-width of the primary pulses. Discussion of the reason: Inertance of magnetization due to the Barkhausen-effect might delay the decrease of the magnetic flux in the magnets.
In 1990/91 the Austrian Engineer H. Schnelzer reproduced the setup using an electric circuit supplying short 7kAmp-pulses by IGBTs, sourced from a car-accumulator. At a demonstration at Scheibbs, 1500 people saw an output power of about 2.1kW (driving a heater and a lamp) for 90 minutes, i.d. more than 3kWh. But the accumulator only had 50Ah/12V, i.e. a power-capacity of maximal 0.6kWh. Furthermore the accumulator did not discharge. It is said, that the device has been inspected and certified by TÜV-München, by measuring input- and output-power and temperature.
Important is an air gap in the yoke as well as high current IGBTs (Driving those IGBTs is today easy doable with Analog Devices ADUM5230 (2.5kV) ADUM7234 (1kV) (Isolation rating), or other Isolated-Gate Drivers). The IGBTs (4 pieces, H-bridge-circuit) of Mr. Schnelzer had a turn-on time of 1µs / ~7000A at 1000V.
