Abstract
DC-DC converters play a vital role in the design of Electric Vehicle (EV) charging systems, LED drivers and power supply units for critical loads like micro-processors. The converters show different behaviors during ideal and non-ideal scenarios. In the present work, synchronous buck and synchronous boost converters operating in Continuous Conduction Mode (CCM) considering the non-idealities were modeled using MATLAB/Simulink. The shift in the output voltage was observed when the Equivalent Series Resistance (ESR) values for the inductor and capacitor were varied. The mathematical models for the converters were derived using volt-sec and amp-sec balance equations for the ideal and non-ideal cases. It was observed that the practical synchronous buck converter showed stability. The practical synchronous boost converter showed instability due to the right half plane zero in its transfer function as a result of which phase reversal occurred at high frequencies.
