  • Electrical isolators
    Patent number: 4054829
    Abstract: An electrical isolator has a transformer with an impedance in series with the primary winding and a high gain amplifier amplifying voltages induced in the secondary winding. Feedback is provided from the amplifier output to produce a current generating flux in the transformer core in opposition to flux produced by current in the primary. Thus the flux density is reduced and with a very high gain amplifier may be made close to zero and well away from saturation.
