Flyback ccm 電流

WebAbstract. Controlling the feedback of off-line flyback converters has often perplexed power engineers because it involves the continuous conduction mode (CCM) and discontinuous conduction mode (DCM) small signal models. Due to the unique feedback compensation mode of the TL431 along with the optocouplers, tuning the feedback parameters still ... WebAC/DC 返馳式控制器 (Flyback Controller) 用於將交流電轉換為穩定、隔離的直流電以供給應用系統。. 交流電首先需整流為高壓的直流電。. 返馳控制器的工作原理類似一個升-降壓控制器 (Buck-boost) ，但採用分離的電感來形成變壓器。. 返馳控制器控制高壓開關 …

WebA flyback operated in CCM reduces peak currents, RMS currents, and MOSFET turn-offloss. However the main disadvantage of a CCM flyback is the lower control loop bandwidth required to compensate for the presence of a right-halfplane zero (RHPZ). 2 …

WebDCM pushes the RHPZ to higher frequencies, making the loop easier to compensate, and therefore offering faster transient response than CCM. Furthermore, when working with duty cycles above 0.5, subharmonic oscillation may occur in CCM flyback converters, which means slope compensation is required.
