The analysis, design, and implementation of an active clamped ZVS forward converter equipped with a soft-switched synchronous rectifier (ACFC-SR), proposed for high-efficiency low output voltage DC-DC converter applications, is presented. One converter — typically the one with the highest output voltage — may deliver current up to its current limit setting, which is beyond its rated maximum. Then the voltage will drop to the point where another converter in the array — the one with the next highest voltage — will begin to deliver current.

Chapter 2: Push-Pull and Forward Converter Topologies 2.1 Introduction The three earliest switching regulator topologies discussed in the previous chapter had the significant drawbacks that the output returns were DC-common with the input returns and that multiple outputs were not possible (except for the restricted case discussed in Sec. 1.3.8). Design the two-output, two-switch forward converter shown in Fig. Consider a flyback converter that draws its input current from a dc voltage source that varies between 185 V and 275 V and produces an output voltage of +12 V at an average load current of 10 A.
