Chapter 13 Flyback Converter, Transformer Design

WebMar 22, 2024 · In [12,13,14,15], boost and flyback converters are integrated by sharing a common switch. In addition to a single switch, a single core is used in . Here, the proposed converter operates boost or flyback mode according to the instantaneous value of the line. However, PF decreases because of the boost operation. The primary winding of the flyback transformer is driven by a switch from a DC supply (usually a transistor). When the switch is switched on, the primary inductance causes the current to build up in a ramp. An integral diode connected in series with the secondary winding prevents the formation of secondary current that would eventually oppose the primary current ramp.
