63 ferroresonant UPS
феррорезонансный источник бесперебойного питания
-EN
ferroresonant UPS
A Usystem which implements output voltage stabilization, by means of a special output transformer, utilizing the constant voltage characteristic of the transformers’ saturated iron core.
To eliminate the current drawn from the inverter by the magnetizing transformer, a capacitor is added to form a parallel resonant LC filter, tuned to UPS frequency.
The ferroresonant method provides output isolation and harmonic filtering. The shortcomings are, relatively low efficiency, increased weight and volume.
[ http://www.upsonnet.com/UPS-Glossary/]Феррорезонансные ИБП названы так по применяемому в них феррорезонансному трансформатору. В основу принципа его работы положен эффект феррорезонанса, применяемый в широко распространенных стабилизаторах напряжения. При нормальной работе трансформатор выполняет функции стабилизатора напряжения и сетевого фильтра. В случае потери питания феррорезонансный трансформатор обеспечивает нагрузку питанием за счет энергии, накопленной в его магнитной системе. Интервала времени длительностью 8... 16 мс достаточно для запуска инвертора, который уже за счет энергии аккумуляторной батареи продолжает поддерживать нагрузку. Коэффициент полезного действия ИБП данного типа соответствует КПД систем двойного преобразования (не превышает 93 %). Данный тип источников бесперебойного питания широкого распространения не получил, хотя обеспечивает очень высокий уровень защиты от высоковольтных выбросов и высокий уровень защиты от электромагнитных шумов. Предел мощности ИБП данного типа не превышает 18 кВА.
