DESIGN, SIMULATION AND TMS320F2407 DSP BASED IMPLEMENTATION OF CONTROLLERS FOR POSITIVE OUTPUT RE-LIFT LUO CONVERTER

摘要

DC-DC converters are widely used in applications such as computer peripheral power supplies, car auxiliary power supplies, servo - motor drives and medical equipments. Luo converter is a recently developed DC-DC converter. Positive output Luo converter performs the conversion from positive source voltage to positive load voltage. Re-lift Luo converter (a boost converter) is highly non- linear and time - variant and shows complex behavior patterns as it works in switch mode. Hence the objective of this work is to design, simulate and implement PI, fuzzy logic and neuro controllers for positive output re-lift Luo converter using MATLAB software and TMS320F2407 DSP. The simulation and experimental results of the closed loop performance of the chosen converter under line and load disturbances are presented and evaluated. They validate the controls developed.
