Abstract:
1. A magnetically controlled switching circuit comprising: a first transistor connected between a first end of a primary of an output transformer and a first single coil secondary of a control transformer; a second transistor connected between a second end of said primary of said output transformer and a second single coil secondary of said control transformer; the base of said first transistor connected to a first end of a first multi-coil secondary of said control transformer; the base of said second transistor connected to a first end of a second multi-coil secondary of said control transformer; wherein said output transformer has a center tap terminal that is connected to an output power source, and said first single coil and said first multi-coil secondaries of said control transformer are in polar opposition to said second single coil and said second multi-coil secondaries of said control transformer.
