Circuit component parameters design for dual-switch flyback converter

For the dual-switch flyback converter operating in CCM condition, each operating mode is established and analyzed, and corresponding state equation is derived in some existing literatures. Since some literatures only use the approximate formulae of single-switch circuit structure to set the circuit component parameters of dual-switch flyback converter, so the designed circuit component values are not precise enough. Based on the operating modes and the state equations of aforementioned literatures, this paper redesigns the circuit component parameters of dual-switch circuit structure, and makes a comparison with of single-switch circuit structure. Finally, the circuit simulation results prove that the circuit component parameters derived in this paper meets requirements.
