Closed loop buck-boost converter using RTW

Designing procedure of Buck-Boost DC/DC converter is discussed in this paper. Application of DC/DC Buck-Boost converter is wide, it include electric vehicles, PV systems, fuel cell, power supplies etc. with high switching frequency. Ruggedness or reliability of DC/DC based power supplies can be increased by paralleling converter or by using number of inductor which carries current in multiple paths and also reduces the ripples. PWM signal for the switching device is obtained by DSP TMS320LF2407 in this paper. Conventional micro controller based Power supplies are not efficient for solar or electric vehicle application. Now a days DSP controller are implemented in many of industry because of more accuracy and its Real time work environment. The simulation is done in CCM mode using Matlab-Simulink and result are validated by implementing the same thing on hardware and its results.
