A long term study of compensation converters allowed to solve the task of designing the structure, the calculation of its elements, the determination of static characteristics and energy performance. Thus remain undeveloped algorithms of their work to ensure a successful use of compensatory converters and independent control of active and reactive power consumption. An algorithm of their work to ensure the optimal use of compensatory converters. This article contains material from GC № 16.526.12.6016 11.10.2011.
