Режимы работы активных элементов. Динамическая характеристика ГВВ. Работа ГВВ на комплексную нагрузку, страница 3

Режим работы генератора при сопротивлении нагрузки больше критического называется перенапряжённым.

3.3. Нагрузочные характеристики ГВВ.

Перейдем к характеристикам ГВВ. Зависимости мощностей от сопротивления нагрузки R_н называются нагрузочными характеристиками. Зависимости напряжений, токов, мощностей от R_н показаны на рисунке 3.
