Abstract

The modern requirements for quality characteristics of voltage, shaped by uninterruptible power supplies, are not created in devices of small power (tens and hundreds watt), produced by domestic and foreign manufacturers. The necessity of a decrease of weight-dimension characteristics for the results in formation of output voltage in the form of the rectangular pulse differ considerably from harmonics. The inverter operating linear-digital principle of structure, for which high efficiency and small nonlinear distortions are typical, is developed. The practical approach has shown that its power efficiency reaches 80% for given quality characteristics of the formed oscillation.
