Flyback Converter: Sometimes called a “buckboost”
converter, this topology minimizes the
required components by using a single transistor
switch and eliminating the need for an output inductor.
During the fi rst half of the switching period,
when the transistor switch is “ON”, energy is stored
in the transformer primary. During the second half
or “fl yback” period when the switch is “OFF”, this
energy is transferred to the transformer secondary
and load. This technique is cost effective because
of the minimum number of components required.
See Boost Regulator, Buck Regulator, Bridge
Converter, Forward Converter, Push Pull Converter
and Resonant Converter.
Foldback Current: See Current Limiting and
Current Limit Knee.
