ABSTRACT:
A system for increasing the voltage handling capacity of an amplifier circuit coupled to a transformer output comprises a transformer secondary winding divided into n sub secondary windings, where n is an integer. A first terminal of a first of the sub secondary windings is coupled to a reference potential. n amplifiers, numbered sequentially 1.ltoreq.m.ltoreq.n as they appear in the amplification circuit with an output terminal of the nth amplifier comprising an output terminal of the amplification circuit, each have an input terminal and an output terminal. An input terminal of the first amplifier is coupled to a second terminal of the first sub secondary winding. An output terminal of each of the n amplifiers is coupled to a first terminal of the next adjacent higher numbered sub secondary winding, except for the nth amplifier, the output of which comprises the output of the amplifier circuit. A first voltage supply is coupled to the first amplifier to provide operating voltage to the first amplifier, and to reference potential. n-1 additional voltage supplies are coupled to respective ones of the n-1 remaining amplifiers to provide operating voltage thereto, and to the output terminal of the next adjacent lower numbered amplifier.
