ABSTRACT:
An electronic transformer is characterized by a pair of out of phase and bilateral current sources, the outputs from which are opposite in phase and control voltages across and currents through respective source and load impedances by combining the voltages in opposition through an amplifier that controls each current source. The electronic transformer has some properties which are essentially the same as those of a conventional magnetic transformer, except that there advantageously is no magnetic field and unwanted magnetic coupling with adjacent components, and the equivalents of leakage reactance, mutual reactance, turns ratio and/or impedance matching may be conveniently and accurately electronically controlled. In addition, the electronic transformer can readily be operated as a switched gain amplifier source, a negative impedance amplifier and/or a positive impedance network generator.
