| Abstract: | Design considerations for a single-stage single-switch input-current shaper (S4ICS) which combines the boost-like front end with a continuous-conduction-mode DC/DC output stage are provided. A complete design-oriented mathematical model is derived for both discontinuous and continuous conduction modes of operation of the boost inductor. The design procedure is illustrated with the example of a 5-V/20-A universal line-voltage range S4ICS forward converter |
