Radio Frequency Oscillator Circuit Breaker

The device provides an on-off solid state circuit breaker which is mechanically controlled to provide a D.C. output voltage pulse having a steep rise time.

Two RF coils 10 and 12 are mounted with a small gap between them. A thin metal disk 14 is mounted on shaft 16. Disk 14 moves in the gap between the coils. Disk 14 has a cutout portion 18. When this is in line with the coils, inductive coupling then takes place. The coils connect to transistor T1 to form a RF oscillator. The oscillator output is A.C. coupled to a transistor rectifier and amplifier circuit comprising transistor T2.

When the disk is in the position which prevents inductive coupling between the coils, the oscillator is off and the output from terminal 20 is zero. However, when the cutout of the disk is in line with the coils, inductive coupling between the coils causes the oscillator to turn on. An output of -V volts is produced at output terminal 20.
