FIELD: electricity.
SUBSTANCE: invention is related to electrical engineering and can be used in distributing mains in order to decrease voltage fluctuations. The transformer contains a stepping switch on the basis of one or several mechanical switches. At switching current is directed through semiconductor switches in order to ensure uninterrupted operation.
EFFECT: simplification of design.
