Controlled rectifier element, which is connected to an inductor, and its use

摘要

A field-effect transistor (F1) which is operated in the reverse direction is used for a controlled rectifier element which is connected to an inductor (W). The field-effect transistor (F1) is controlled via a current transformer (Ü) such that current can flow only during the demagnetisation of the inductor (W). This arrangement is suitable especially for low-power voltage converters having a pulsed current with gaps. <IMAGE>
