In the present work, three different methods for obtaining the DC response for modeling practical DC-DC buck and boost converters operating in continuous conduction mode (CCM) are demonstrated using MATLAB/Simulink. The method of selection for inductor, diode, and MOSFET for a DC-DC converter is discussed in detail. The governing equations for the non-ideal converters were derived using volt-sec and amp-sec balance equations. Mathematical modeling of basic converters was carried out using ‘commonly used blocks' reducing the dependence on SimPower System tool box in Simulink. The non-ideal parameters in the converter caused a drastic variation in the duty cycle and output voltage which in turn had an adverse effect on the efficiency. The transients in output voltages and inductor currents were observed. In addition, a Li ion polymer battery was mathematically modeled. Accurate battery modeling for pulse charging was proposed. A comparative analysis of 1, 2, …, 5 RC pair/s modeling of the battery was presented.
