Abstract
Soft switching in flyback converters using a fixed dead time is presented. Embodiments disclosed herein relate to switching circuits and more particularly to soft switching in single stage isolated flyback converters. Embodiments herein disclose systems for soft switching in single stage isolated flyback converters operating in boundary control mode, by incorporating a fixed dead time.
Claims8
A flyback converter (100) comprising
- a switch (SW) (103) connected to primary windings of a transformer (T) (104);
- a capacitor (Cr) (101) connected across the switch (SW) (103);
- and
- a diode (Ds) (105) connected to the secondary windings of the transformer (T) (104);
- wherein a control input to the flyback converter (100) comprises a fixed dead time in a Boundary conduction Mode (BCM), wherein the fixed dead time is introduced before turning ON the SW (103).
