15 KVA static uninterruptible power conditioner

The Army needs a light weight, reliable and economical uninterruptible power conditioner (UPC) capable of converting those input voltages and frequencies from various power sources to power conforming to military standards. Only static UPC was assumed to have the potential to meet military objectives. The alternative approaches vary in degree of risk, cost, weight and performance growth potential. The circuitry and performance characteristics for three approaches are discussed. The limitations of existing solid state devices are discussed. Predictions of physical characteristics for future UPC utilizing these technologies and circuits are provided.
