The invention is a type of signal amplifier that uses electromagnetic induction to boost the signal received from either an electromagnetic source or an acoustic source.
The invention routes a signal through the primary of a step up transformer while the flux within the transformer is increasing, and then routes the signal through the secondary in the opposing direction while the flux is decreasing. The potential energy in the form of magnetic flux is released at a voltage and current that differs from the voltage and current that generated the flux. Releasing this potential energy with a higher voltage creates a high “field impedance” that maximizes energy transfer.
A signal that emanates from an electromagnetic source or an acoustic source is routed through the primary of a transformer building up flux in the core of the transformer. When the flux reaches its highest absolute magnitude, at π/2 radians, the signal is routed through the secondary in the opposing direction, such that current continues flowing in the direction it had been in the secondary. The flux that has been accumulated in the core begins to ebb as it does in the normal operation of a transformer, but the voltage and current of this phase are altered on the signal side of the transformer. This voltage and current correspond to the electric and magnetic fields being received by the antenna or an electro-acoustic bridge. By having a secondary that converts the flux to a higher voltage and lower amperage relative to that which generated the flux from the primary, the ratio of electric to magnetic field of this portion is skewed to be higher. This skewing of the ratio of electric to magnetic fields creates a higher field impedance, which maximizes power transfer from the signal source. When the flux and current reaches its minimum, at π radians, the signal is routed back to the primary again until flux reaches its maximum in the opposing direction, at which point it is routed to the secondary in the opposing direction, as it had been at the π/2 radians portion of the cycle.
The output of the transformer is routed from the secondary in the opposing direction during the portions of the cycle where flux is increasing, 0 to π/2 and π to 3 π/2, and from the primary during the portions of the cycle where flux is decreasing, π/2 to π and 3 π/2 to 2 π.
In the attached circuit, the design has been simplified by using a common ground between the primary and secondary. Note the ground on the secondary is on the side opposing from the primary.
The same connections of components can be used substituting triodes, tetrodes, or pentodes for the transistors. Krytrons may also be used.
An alternative design would be to use a relay or solid state relay. One DPDT relay could replace the eight transistors used to route the input and output to the primary and secondary.
Another possible alternative is to use thyristors to route the input and output.
The signal processing that drives the switches could use a capacitor for its phase shifting and invert the output. Also, an inverting integrator op-amp or a microcontroller could provide the signal processing functionality needed to run the switches.
