The aim of the research is to increase energy efficiency, controllability and stability of electrical distribution networks, creation of high-efficiency switchmode converters, by developing scientific base, mathematical and physical models, circuitry and control systems of high-efficiency converters. New circuit solutions of converters have been developed, which have a smaller number of power semiconductor components and inductive components and a reduced cost compared to the known ones, while maintaining comparable performance. Experimental samples of welding inverter sources are made, on which the efficiency of the proposed ideas is confirmed. New circuit solutions and methods of control of the hybrid compensator of nonactive power, which consists of the thyristor switched capacitor bank with the serial active power filter are developed. Implemented flexible configuration of the operating mode with regulation of the compensating current depending on its harmonic number. This allows to ensure stable operation of the compensator in networks with a significant level of non-sinusoidal voltage distortion. The structure of the block uninterruptible power supply system for households and small businesses is proposed. Product Description popup.authors Burlaka Volodymyr V Kislyak V. G.
