Flyback ccm type ii compensation
WebOne of the most important factors in the design of a flyback converter power supply is the design of the transformer. The main advantages of the flyback circuit are cost, simplicity and the ease of adding multiple outputs. Flyback topologies are practical and lowest cost for systems up to 100W. Flyback transformer design is a somewhat iterative WebApr 25, 2009 · MooseFET. Jan 1, 1970. 0. Apr 25, 2009. #3. I've been reading different opinions on when to apply slope. compensation on a current mode SMPS in CCM. If for example my flybacks. worst case maximum duty is 41% and it's not deep in CCM is slope.
