Single-switch two-output flyback-forward converter operation
TLDR
In this article, a double power converter with fully independent regulated outputs is introduced, which results from magnetic integration of flyback and forward power converters, and the derived converter shares a single power switch having a single magnetic component.Abstract:
A double power converter with fully independent regulated outputs is introduced. The proposed topology results from magnetic integration of flyback and forward power converters. The derived converter shares a single power switch having a single magnetic component. Also, only one standard pulsewidth modulation (PWM) integrated modulator is needed in order to keep independent closed-loop control of both output voltages. The double regulation may be sustained over a wide spread of current loads. Boundaries of full regulation and experimental results are presented.read more
