ISOLATED FLYBACK CONVERTER

摘要

A flyback converter has a sub-nanofarad capacitor disposed between the primary winding and the secondary winding of a transformer included in the flyback converter. A controller in the flyback converter co-optimizes the switch period and width such that the flyback converter operates substantially at peak efficiency via the use of a novel set point and control-signal. A model of global optimal control is provided via a novel characterization and analysis method.

主权项

1. A flyback converter comprising:
a transformer including a primary winding and a secondary winding; a controller configured to generate a control signal to control the transformer; and a capacitor connected between a first terminal of the primary winding and a second terminal of the secondary winding, the capacitor having a value in the sub-nanofarad range.
