Opis: The purpose of this work was to develop and test the switched capacitors-boost converter (SC-BC), which can be used for stepping up voltage by a factor of at least ten driving energy harvesting applications. Extensive mathematical modelling of SC-BC was done for obtaining its nonlinear model and equations of multiple static characteristics. Simulations of SC-BC and its simplified models were done within a PSIM environment. The choice was made for closed-loop to use the combination of a PI controller and sliding mode control due to the robustness requirements and excellent closed-loop dynamics. Control was implemented on digital signal processor TMS320F28335 within a MATLAB/SIMULINK environment. Lastly the open and closed-loop experiments were done on a real SC-BC prototype.Ključne besede: switched capacitors, boost converter, sliding mode control, energy harvesting, mathematical modellingObjavljeno v DKUM: 14.10.2015; Ogledov: 2577; Prenosov: 229 Celotno besedilo (5,47 MB)
