WebSingle stage critical conduction mode (CrM) flyback converters require different design considerations compared to fixed frequency or quasi-resonant (QR) flyback
WebMar 12, 2014 · A variable on-time (VOT) control strategy for a critical conduction mode (CRM) flyback power factor correction (PFC) converter with low total harmonic distortion (THD) and high power factor (PF) is proposed in this paper. By using input voltage and the voltage across the auxiliary winding of the flyback transformer to modulate the turn-on … Introduction. Flyback converters are often used in switch-mode power supplies for AC/DC and DC/DC conversion, especially for the low-to-mid power range (about 2W to 100W). In this power range, flyback converters offer a very competitive size, cost, and efficiency ratio. A flyback converter’s operation is based on a … See more A flyback converter’s two operation modes seem very similar, but each has its own set of advantages and drawbacks. It is very important for designers to consider these advantages and drawbacks during the design process, … See more DCM offers higher efficiency than CCM, due to the lack of reverse recovery loss on the diode and a softer turn on of the MOSFET. However, if the duty cycle is too small, then the … See more Regarding regulation and stability of the system, a flyback in DCM is easier to compensate than a flyback in CCM. This is because the problematic right-hand plane zero (RHPZ) appears and introduces instability at lower … See more Regarding the transformer size, DCM requires a smaller inductance, which theoretically means it can use a smaller transformer. However, due to the incremented spikes … See more
