The article investigates a new technical solution proposed by the author, which is a three-phase two-bridge compensating converter of a parallel type with one commutating link. It consists of a three-phase capacitor battery and a three-phase group of fully controlled devices (for example, IGBT). The main objective of the study is to bring the conditions under which the efficient use of the equipment of the commutating link of the converter is ensured and such conditions for the formation of the capacitor voltage are created under which the converter acquires the ability not only to compensate for its own reactive energy, but also to generate it into the power supply network. The scope of the research includes the analysis of the operating modes of the compensating converter when controlling the transistors of the commutating link with pulses of double, quadruple and eightfold frequency. The research methodology is based on the harmonic analysis of the curves of the phase current of the capacitor battery. The general conclusion is obtained as a result of comparing the analysis results at different frequencies of the control pulses of the transistors of the commutating link.
