Abstract :
In order to determine the feasibility of improving the performance of a power conditioning component, a first order thermodynamic analysis was conducted on the effects of refrigeration for a general switching device and ceramic capacitors. In a separate investigation, it was found that by converting the power output of the generator from 4160 VAC, 60 Hz to 50 VAC, 1000 Hz a mass saving of 65% was realized in a power conditioning console for radar applications. Cryocooling switching devices and capacitors to optimum temperatures can potentially improve the savings to 80%. The general conclusion of this analysis is that the performance of power conditioning components can be enhanced by cryocooling while reducing the mass and volume effectively resulting in a more compact and easily maneuverable radar system power supply
