Annotation: Modes of operation of three-phase frequency converter with dc-link are considered. Converter based on active rectifier and self-excited voltage inverter has active-inductive load. Electromagnetic processes analysis allows creating single-phase equivalent circuits and taking off analytic relations between input voltage with output voltage and between load current and input current. Converter regulating characteristics are also obtained.
