A FORWARD CONVERTER WITH AN INDUCTOR COUPLED TO A TRANSFORMER WINDING

摘要

A forward converter includes a chopper transformer (T1) having a primary winding (T1W1) and one or more secondary windings (T1W2, T1W3). A corresponding rectifier (DOUT2) and a corresponding filter capacitor (CFILTER2) is coupled to each secondary winding. An inductor (Lres) is coupled in series with the primary winding. A low impedance current path that includes the corresponding rectifier is formed between each secondary winding and the corresponding filter capacitor. The inductor limits the rate of change of the current (IDOUT2) in each current path.
