ONE-STROKE FLOW CONVERTER WITH ONE TRANSFORMER AND WITH TWO ELECTRONIC SWITCHES PROTECTED BY PROTECTIVE MEASURES

摘要

Disclosed is a single-ended through-flow frequency converter with a transformer (5) whose primary winding (51) is connected, via two electronic switches (41, 42) controlled in synchronism and two diodes (43, 44), to an input voltage source. In order to ensure optimum balancing of the switches (41, 42) with lowest-possible losses, the invention calls for a protective circuit consisting only of an inductance acting on the primary-coil side of the main circuit, a series-connected CD circuit (33, 34) and a series-connected LD circuit (31, 32). The throuhg-flow frequency converter is suitable for use in power-supply modules designed to power electrical communications system components and for use in combinatorial circuits.
