Abstract : Efficient, light-weight power conditioning equipment was investigated in the area of AC to AC transformation, where AC of a variable frequency is to be transformed efficiently into AC of a fixed frequency at a significant power level. This task, which follows an earlier contract where a bridge chopper technique was developed for DC to AC power conversion, had as its objective the development of a system utilizing the capacitance effect of a storage battery in addition to its storage capability to permit the conversion from AC over output in the event of a source failure. The effort was conducted in two phases. The first phase was an investigation of the methods which could be used to control the flow of power from the source AC generator to a storage battery link and from the battery to the waveform generator and to the output circuit. The second phase was to select a method which would represent an optimum of the approaches considered and then breadboard and evaluate the components in a system configuration. (Author)
