Abstract :
A simplified design procedure is described for an isolated output coupled inductor SEPIC converter. The authors had a requirement for a converter to supply an isolated 24 V DC at 4 A, meet DO-160 emission requirements, and operate from a DC voltage source that varied from 11 to 150 V with 14% peak-to-peak audio frequency ripple (rectified three-phase AC from a permanent magnet generator). This paper shows how the significant design issues were dealt with, and how well the initial design tests met the goals
