Radiation emitter with pulse width and frequency control - has transistor for applying power to emitter in pulse form under control of switching amplifier circuitry

摘要

The system includes a radiation emitter which is pulse driven by high current, low voltage full wave rectified direct current electrical power. Pulse frequency and width are controlled to provide periods of nonemissive operation sufficiently longer than the periods of emissive operation to maintain a desired emitter temperature. An electrically conductive case mounts the emitter in electrically conductive relation with it and provides one current path to the emitter. The controller is responsive to a trigger pulse for switching an amplifier.
