METHOD FOR DISTRIBUTION, SUMMATION, AND ADJUSTMENT OF POWER OF ELECTRICAL ENERGY FLOWS DURING TRANSFORMATION OF THREE-PHASE VOLTAGE INTO CONSTANT Russian patent published in 2022 - IPC H02M7/10 H02M1/88 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to semiconductor equipment; it can be used at transformer conversion substations of factories and transport enterprises. Electrical energy of three-phase alternating voltage comes to primary windings of single-phase three-winding transformers. Secondary sectioned windings of single-phase transformers of three phases of a base and adjustable electrical energy channel are open between each other for elimination of short circuits of windings and are connected to rectifiers. Due to distribution of energy flows along three single-phase transformers and along sectioned galvanically separated secondary windings in each phase, inter-phased short circuits by semiconductor rectifier devices are eliminated.

EFFECT: provision of energy-saving transformation of three-phase alternating voltage into constant, stabilization of voltage at an output, and increase in electromagnetic compatibility of a transformation device with a power supply system.
