TWO STATE-MODULATION TECHNIQUES FOR POWER SYSTEMS.
Abstract
This is the second semi-annual report on an investigation of techniques and circuitry based on the use of two-state modulation systems, directed toward development of improved advanced power conditioning equipment. Improvements are sought with respect to smaller, lighter-weight, more efficient and, hence, highly reliable power conversion systems for military use. Theoretical and experimental studies are being pursued through construction of several experimental breadboard models: a regulator unit which supplies a regulated 28vdc output voltage at up to 50 amperes current drain from unregulated dc inputs, and a converter unit which supplies multiple regulated high voltage dc outputs, 700v and 300v, from a nominal 28vdc input. Future work is programmed in the area of power inversion. This report gives a detailed description of the experimental work accomplished. Two research prototype units employing the current controlled Two State Modulation System were designed and contracted during this reporting period. Circuit descriptions, waveforms, performance capabilities and limitations of the units are discussed. Problem areas encountered are outlined along with recommendations for future R and D in components which are causing current system limitations.
