WebThe flyback topology is essentially the buck-boost topology that is isolated by using a transformer as the storage inductor. The transformer not only provides isolation, but by varying the turns ratio, the output voltage can be adjusted. Since a transformer is used, multiple outputs are possible. WebThe flyback topology [Figure 10] uses separate windings on a transformer and there is only magnetic coupling between the primary and secondary windings. The current in the primary winding goes to zero with relative high di/dt. Only the energy stored in the leakage inductance and capacitance between windings and on the switch node slows that down. can i freeze youfoodz mealsWebApr 18, 2010 · The buck-boost just uses a simple solenoid to store the energy.
