Flyback qr

WebA quasi-resonant flyback is simply a discontinuous current mode (DCM) flyback with a valley switching turn on. It is also known as variable frequency or valley switching flyback and is largely used in low power switch mode power supply application such as charger, adapter and auxiliary supply. Webflybacks, QR flybacks are forced to operate in DCM or on the edge of DCM/CCM operation, referred to as transition mode (TM) or critical conduction mode. Figure 2 …
