FIELD: electrical engineering; voltage converters for feeding ac electrical machines. ^ SUBSTANCE: proposed dc voltage converter that incorporates provision for feeding additional single-phase current consumers and for equalizing loads of different-rating ac consumers has set of input filters, single-phase inverters, step-down transformers, bridge rectifier, and LC filter with three-phase inverter connected to its output for feeding induction motor. Secondary windings of transformer are interconnected in parallel and have leads for feeding single-phase current loads; all transformer windings are disposed on common magnetic circuit. ^ EFFECT: enlarged functional capabilities. ^ 1 cl, 1 dwg |
