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...

Active Clamp Zvs Flyback Converter with Output Voltage Douler

Active-Clamping Quad-Flyback Converter

An active-clamping quad-flyback converter is proposed to achieve zero voltage switching (ZVS) for all power switches. The secondary sides of quad-flyback converter are connected in parallel to share the load current. Thus, the transformer copper losses and the conduction losses on the output diodes are reduced. Activeclamping part including one auxiliary switch and one clamp capacitor can relea...

High-power-factor Sinusoidal-output-waveform Converter Based on the Flyback Topology for Ac Ups

I.Introduction. Everyday, the number of critical loads connected to the utility line increases. These critical loads need a highly reliable power supply. There has been reported several solutions to this need, some of these solutions include ferroresonant voltage regulators, variable inductance regulators, tap changing regulators and uninterruptible power supplies (UPS) [1]. Among the UPS solut...
