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 radiation tolerant high-power DC/DC converter is disclosed. The converter does not incorporate radiation-hardened parts, but instead uses p-channel FET switches that have a negative gate threshold voltage. With exposure to radiation, the gate threshold voltage decreases, becoming more negative. Thus, the gate is still controllable.

Abstract: A method of producing an economical DC/DC converter that efficiently produces a relatively low output voltage and operates in a high ionizing radiation dose environment such as found in spacecraft and particle accelerator applications. That is, the converter comprises two P-channel FETs, a switching means for switching conductivity between the two P-channel FETs, and output means for outputting an output voltage. The output voltage being a step-down voltage that is unaffected by high-ionizing radiation such that is found in space or particle accelerators.

Abstract: A high voltage power supply having a low voltage input comprising a transformer having a primary winding, an input switching means coupled to the primary, first and second groups of secondary windings each of which are sub-divided into a plurality of component windings, and voltage converters coupled to each of the component windings for producing series output voltages of opposite polarities across the groups of secondary windings. First and second output switching means alternately switch the series output voltages to provide an intermediate voltage at a common point which is the input of a diode capacitor multiplier circuit thereby producing at its output a high voltage output.

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 an 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.

Abstract: A digital tachometer arrangement in which pulses resulting from rotation of a shaft, are counted over a predetermined time interval. The time interval is established by counting pulses from a high frequency oscillator. The counting of pulses from the high frequency oscillator is begun only at a predetermined instant when the pulses from the rotating shaft attain a positive edge. Relating the beginning of the time interval precisely to a predetermine edge of the pulses from the rotating shaft, provides for a stabilized display which counts the pulses from the shaft during the preset time interval. The count of the pulses from the rotating shaft over the preset time interval, is proportional to the rotational speed of the shaft, and is displayed on a digital readout connected to a binary-coded decimal counter receiving pulses from the rotating shaft.
