Power supply switching circuit that normally uses a single transistor. During the first half of the switching period, the transistor is on and energy is stored in a transformer primary. During the second half period, this energy is transferred to the transformer secondary and the load.
When you have a power supply that uses a single transistor as well as a flyback diode, this is referred to as a flyback converter. read more...
The flyback converter is the simplest type of switcher. In most cases, it uses one switch and only needs one magnetic element - the transformer. Flybacks are limited to outputs of generally lower than 200 Watts.
A isolated Buck-Boost SMPS topology in which, during the first period of a switching cycle the energy is stored in a inductance and during the second period this energy is transferred to a different winding of the same inductor and into the load.
Also called a buck-boost converter, this topology typically uses a single transistor switch and eliminates the need for an output inductor. Energy is stored in the transformer primary during the first half of the switching period when the transistor switch is on. During the second half or flyback period when the transistor is off, this energy is transferred from the transformer secondary. Also see Boost Regulator, Buck Regulator, Bridge Converter, Forward Converter, Push-Pull Converter and Resonant Converter.
The Flyback converter is a DC to DC converter with a galvanic isolation between the input and the output(s). It has the same structure as the buck-boost converter, with a transformer instead of an inductor. Thanks to this transformer, it can achieve very high conversion ratios.
