DC-DC converter.

摘要

A switched mode power supply has a sense transformer (TX2) with three windings. A first (primary) winding (WD) is in series with the primary winding (WP1) of the power transformer (TX1). Current regulation of the output is provided via a second (sense) winding (WS). Voltage regulation of the output is provided by a further (third) winding (WC) being connected in parallel with the secondary winding (WP2) of the power transformer for producing isolated feedback of an output voltage error signal using the sense transformer (TX2) as a current summing transformer
