Electric vehicles (EV's) are the promising technology of today's world. Electric vehicles use battery as the primary source of input and batteries are controlled by the help of DC-DC converters. Hence the DC-DC converter modeling and simulation plays a vital role in understanding its dynamics. In this paper, mathematical modeling of a non-ideal asynchornus buck boost converter is modeled using the basic equations of volt-sec and amp-sec balance. The transfer functions of constant voltage $\frac{\widehat{\mathrm{v}_{0}}}{\hat{\mathrm{d}}}$ for non - ideal asynchronous and synchronous converters are also modeled using State Space averaging (SSA) technique and analyzed using MATLAB software. To validate the obtained Gvd Generalized Circuit averaging technique is used with LTspice simulation tool. Gvd obtained from different control techniques were found to be similar. However, a small variation is found in LT-Spice tool.
