    Abstract: The present invention provides a radiation-tolerant-solid-state-relay without radiation-hardened parts. A p-channel MOSFET provides power-switching functionality. In further detail, the solid-state-relay comprises a bias section, a control section, and a power-switch section. The bias section provides a voltage bias to the control section, the control section provides a control voltage to the power switch section as a function of the voltage bias, and the power switch section provides a switching voltage to the P-channel MOSFET as a function of the control voltage.

    Abstract: A radiation hardened active OR circuit for providing a controlled electrical response in radiation-intensive applications. The circuit can include a first voltage source; a second voltage source; a comparator for sampling the first voltage source and the second voltage source; a first switch; and a second switch. The comparator can select a higher magnitude of the first voltage source and the second voltage source and connects the higher magnitude of the first voltage source and the second voltage source to a common output by steering a drive signal to one of the first switch or the second switch.

    Abstract: A radiation hardened motor drive stage utilizes a non-radiation hardened P-channel FET switch. The radiation hardened motor drive stage includes a non-radiation hardened P-channel FET switch that is connected three (3) pairs of upper and lower switch blocks or legs wherein the output of each pair is connected to a motor winding switch terminal. The upper switch blocks or legs are connected the P-channel switch a. The lower switch block or legs are connected to a negative power bus. The negative power bus permits the N-channel FETS or IGTS within the switch blocks or legs exposed to ionized radiation to be controlled, even when their gate threshold voltage has dropped below zero volts.

    Abstract: A portable high pressure sodium lamp lighting system is mounted on a mobile cart, the cart carrying a mobile power supply in the form of a automotive type battery. The portable lighting system employs a standard high pressure sodium luminaire designed to be driven by 115 volt 60 cycle utility generated power. A DC to AC converter is employed which converts the DC battery supply to a 115 volt simulated 60 cycle supply. The AC characteristic is simulated by generating a quasi-square wave form which approximates a 60 cycle characteristic when driving the luminaire.
