Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

A paper proposes a circuit design of single-phase forward inverter source with increased power factor. A peculiarity of the source is absence of additional power inductive components, reduced capacity of storage capacitor in direct current circuit and simplified limit circuit of its charging current. The source has increased open circuit voltage, which does not depend on mains voltage and allows providing easier arc ignition in manual arc welding. Current consumed from mains is 30–45 % lower than in «classical» inverter sources without power factor corrector due to increased power factor. 11 Ref., 1 Figure.
