摘要
The modem requirements to quality characteristics of voltage, shaped by uninterruptible power supplies, are not created in devices of small power (tens and hundreds watt), produced by the domestic and foreign manufacturers. The necessity in a decrease of weight-dimension characteristics for them results in formation of output voltage in the form of the rectangular pulse considerably differing from harmonic. On the chair for the theory of electric circuits of the St.-Petersburg state university of telecommunications in the name of Prof. M.A.Bonch-Bruevich the inverter operating linear - digital principle of structure, for which high efficiency and small nonlinear distortions are typical, is developed. The practical approbation has shown, that its power efficiency reaches 80 % at given quality characteristics of the formed oscillation.
