Application Factors Affecting the Weight of Aerospace Static Inverters

Abstract

The purpose of this paper is to reconcile the wide range of weights quoted for aerospace static inverters of the same VA rating. The inverters discussed are of conventional input and output: 15 to 500 vdc input and 400 cps sine wave output. Specification and application factors affecting inverter weight are tabulated. Graphical relationships are given for the effects of some factors for which relationships can be defined. Trends are indicated for the weight effect of factors for which graphical relationships are not given. The data presented should be useful to systems designers, in avoiding undue inverter weight, by proper specification and application of static inverters.
