ABSTRACT:
This disclosure consists of two fluxgates, a signal generator and an invertor transformer. Signal current flowing from right to left through the signal coil of a first fluxgate allows power current flow from left to right through the power coil, adding energy to the signal current and hence on through a second fluxgate trigger coil. Simultaneously signal current, enhanced by the induced power current, is moving from left to right through the signal coil on the second fluxgate and prevents power current flow from left to right in the power coil of the second fluxgate. Power current flowing through the trigger coil on the second fluxgate reduces energy stored in the core, allowing the signal current to reverse cycle. Energy induced into the signal circuit by the power coil passes back into the power circuit through the trigger coil and the collapse of the magnetic field upon completion of the second quarter of the cycle. This action produces a pulse of one-half cycle and upon reversal of the signal current the above cycle is duplicated in reverse and alternate pulses are produced. These alternate pulses travel in opposite direction through separate primaries in an invertor transformer producing alternating current in a secondary circuit.
