Abstract

Предложены способ и система для переключения нагрузки с одного источника напряжения переменного тока на другой источник напряжения переменного тока. Временный источник напряжения подсоединяют к нагрузке и первому источнику напряжения через резистор. Подсоединяют второй источник напряжения к нагрузке. После этого временный источник напряжения отсоединяют от нагрузки. Временный источник напряжения может быть независимым от первого и второго источников напряжения или может получать напряжение от первого или второго источника напряжения, а подсоединение или отсоединение осуществляют посредством механических переключателей посредством тиристоров либо посредством параллельно или последовательно соединенных механических переключателей и тиристоров.
