Abstract This paper presents practical design guidelines for off-line flyback converter employing FPS (Fairchild Power Switch). Switched mode power supply (SMPS) design is inherently time consuming job requiring many trade-offs and WebThe flyback converter is an isolated power converter. The two prevailing control schemes are voltage mode control and current mode control. In the majority of cases current mode control needs to be dominant for stability during operation. Both modes require a signal related to the output voltage.
