A common part used to create a high voltage is a CRT flyback transformer, having been a ubiquitous junk pile component. So many attempts to use them rely on brute force, with power transistors in ...

The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...

The power lost in a dissipative clamp is related to energy stored in the leakage inductance of each switching cycle. When the FET is on, the current in the primary winding of the transformer increases ...

The flyback design is a switched-mode power supply (SMPS) that’s been used for 70+ years and still going strong. This supply—also called a power converter—has two distinct operating phases, with power ...

The choice between a flyback or single-ended primary inductance converter (SEPIC) topology often ends with the designer choosing the most familiar one, but that’s not always the right option, say John ...

When developing TOPSwitch flyback power supplies, transformer design is usually the biggest stumbling block. Flyback transformers are not designed or used like normal transformers. Energy is stored in ...
