Epcos. Ferrites and Accessories for xDSL Applications

Компенсация пилообразных изменений для преобразователей работающих в токовом режиме. By Christophe Basso, Applications Manager, ON Semiconductor, Toulouse, France A peak current-mode power supply is subject to subharmonic oscillations if two conditions are met: the converter operates in the continuous conduction mode (CCM) and the duty-cycle is close to or above 50%.

5 страниц. November 2009. Applications & Cases. A broad range of EPCOS varistors satisfies the extended requirements of the reissued UL® 1449. The third edition of this overvoltage protection standard went into effect on September 29, 2009. In recent years, the European electrical and electronics industry has reworked the safety standards for surge protective devices (SPDs) several times – in some cases with significant changes: thus the fi...

5 страниц. До настоящего времени расчет магнитных характеристик индуктивных компонентов был весьма сложным. Благодаря разработанным компанией EPCOS новым программным средствам процесс разработки ферритов и расчёт магнитных характеристик ферритов стали достаточно легкой задачей. Ферритовые материалы компании EPCOS, такие как N27, N67, N41 и N87, широко используются в трансформаторах и дросселях, применяемых в импульсных источниках питания. Из эти...
