Energy-Efficient Technologies in Test Beds with Application of Single-Phase Reversible Converters
Abstract
The lowering of losses and refinement of electrical energy in electric mains is one of the most important tasks at solution of a resource economies problem, in particular, energy savings in industrial technological systems and complexes. One of the possible candidate solutions of the given problem is the application of reversible voltage converter (RVC).
In article the results of experimental investigating of a single-phase RVC, operating under of higher harmonics active filter and reactive power compensation and also for the first time of offered single-phase load-feeding device intended for a test and research of electric energy converters and other electrotechnical equipment as on direct and alternating-current are given. The considered devices ensure lowering of power consumption and improvement of electrical energy quality. The high operate reliability and noise stability of a control system and also improvement bulk-overall indices of RVC is reached at the expense of application of integrating sweep converters and unipolar-modulation at switching power valves. The results of operation are used in the automized laboratory complex «Energy-efficient power electronics».
Keywords: reversible voltage converter, active filter, reactive power compensator, load-feeding device, integratingsweep converter, thyristor converter, frequency converter.
