Flyback converter wikipedia

WebThe flyback converter is a smps-converter with a galvanic isolation between the input and the output (s). To some extent the flyback converter can be seen as an isolated buck-boost converter. WebJan 12, 2015 · Two operating states of a flyback converter (wikipedia) When the switch is turned on, current is drawn through the transformer, increasing the magnetic flux of the transformer core. The voltage across the secondary is negative, reverse biasing the diode. Energy is stored in the transformer in the form of magnetic flux.
