Abstract

In the present work, a voltage tracking controller is developed for DC-DC Buck-Boost converter using software model. The software developed can track the voltage and the mode of operation (Buck or Boost), which depends on the value of the duty cycle ratio (D). The error between π‘‰π‘œπ‘Ÿπ‘’π‘“(reference voltage) and output voltage is minimized by using step input as reference. The simulation results show that the designed software controller can successfully track the voltage with low error and with short settling time. The values for the Buck-Boost circuit components, the capacitor and the inductor, are tuned and selected so that the system is robust for large variation in the input voltage.
