High Energy, Short Duration Pulse System
US Patent:
4135099, Jan 16, 1979
Filed:
Sep 15, 1977
Appl. No.:
5/833624
Inventors:
Richard J. Fiedor - Penn Hills PA
Maurice H. Hanes - Murrysville PA
Maurice H. Hanes - Murrysville PA
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
G02B 2700
US Classification:
250551
Abstract:
A system for switching a high energy, short duration pulse from a high energy source to an impedance matched series load. A light activated semiconductor device having a rectifying junction is serially connected between the source and the load, and another light activated semiconductor device is connected in parallel across the load. A fast rise time laser light source sequentially activates the series connected device to initiate the energy pulse, and then actuates the device paralleled across the load to short circuit the load and terminate the energy pulse.
Light Activated Switch System Having High Di/Dt Capability
US Patent:
4204116, May 20, 1980
Filed:
Jul 24, 1978
Appl. No.:
5/927441
Inventors:
Michael W. Cresswell - Plum Borough PA
Richard J. Fiedor - Penn Hills PA
Richard J. Fiedor - Penn Hills PA
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
G01D 534
US Classification:
250229
Abstract:
A light activated semiconductor switch comprises a light source for activating a light activated semiconductor device. A remote controllable light deflecting device is interposed between the light activated device and the light source for directing the light source onto the light activated device at a specified time in the rise time of the light source in response to a signal in order to decrease the switching time of the light activated device.
