Three-Output Flyback Converter with Synchronous Rectification for Improving Cross-Regulation and Efficiency

Low-power flyback converter with synchronous rectification for a system with AC power distribution

IEC 1000-3-2 regulations impose a reduced harmonic content on any converter with an input power higher than 75 W. However, if the power architecture of the system is based on small on-board converters, and the total power is higher than 75 W, IEC regulations must be fulfilled although each individual converter need not comply with the regulations. In this paper, one of the different possible so...

Active Clamp Zvs Flyback Converter with Output Voltage Douler

Modeling of Cross-regulation in Multiple-output Flyback Converters

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-cla...

SOW Forward Converter With Synchronous Rectification And Secondary Side Control

This article reviews a new technique for secondary side control of a DC-DC converter without using an auxiliary bias supply. A unique primary side start up circuit is used to drive the primary side power transistor. Gate pulse information for the primary transistor is transmitted through a pulse transformer that is shown to be smaller than an opto-isolator. The discussion includes transformer-r...
