Summary: | 碩士 === 國立虎尾科技大學 === 電機工程系碩士班 === 106 === This paper mainly establishes the switch converter model and design digital controller. A typical step-down synchronous rectification converter is used as the main architecture, and the controller core uses the DSP TMS320F28335 from Texas Instruments. The mathematical model picks infers the switch the small signal mathematical model transfer function, can design the PI controller, by the simulation software PSIM confirmation controller design, with the spreadsheet confirmation mathematics formula, with the actual hardware measuring, achieves three aspects the confirmations. The digital control simulates software PSIM to take the auxiliary tool, analog the control in the simulation software, the fast transformation digital control, burns into to DSP, finally completes design the digital control
