Modeling of Cross-regulation in Multiple-output Flyback Converters

چکیده
In this paper, complex operation of multiple-output flyback converters is explained in terms of the extended cantilever magnetics model. Analytical results are derived that can accurately predict steady-state cross-regulation properties of a converter with any number of outputs and with arbitrarily complex magnetics configuration. Two snubber configurations are considered: a passive voltage-clamp snubber and an active-clamp snubber. Predictions of the model are verified by experiments. The analytical models are the basis for a discussion of magnetics design guidelines that can result in improved cross-regulation in multiple-output flyback converters.

متن کاملA New Single-Phase Single-Stage AC-DC Stacked Flyback Converter With Active Clamp ZVS
Single-stage AC-DC converters integrate an AC-DC front-end converter with a DC-DC backend converter. Compared with conventional two-stage AC-DC converters, single-stage ACDC converters use less components and only one controller, which is used to regulate the output voltage. As a result, the cost, size and complexity of AC-DC converters can be reduced, but single-stage converters do not perform...
متن کاملAN-4140 — Transformer Design Consideration for Offline Flyback Converters Using Fairchild Power Switch (FPSTM)
For flyback coverters, the transformer is the most important factor that determines the performance such as the efficiency, output regulation and EMI. Contrary to the normal transformer, the flyback transformer is inherently an inductor that provides energy storage, coupling and isolation for the flyback converter. In the general transformer, the current flows in both the primary and secondary ...
متن کاملReachability Analysis of Transformer-Isolated DC-DC Converters
Various mission-critical applications necessarily require a transformer in switching converters to obtain DC isolation between the converters’ input and output. Since DC-DC converters are the switching devices, these are modeled as hybrid automata. We present hybrid automaton modeling of two main types of transformer isolated DC-DC converters, namely, flyback and forward converters. We have als...
