haos, also called strange behavior, is currently one of the most exciting topics in nonlinear systems research. When nonlinearity is present in a system, there exist a
large number ofparameters where the steady state response is bounded, but aperiodic. Instead, the response becomes erTatic with a broad continuous frequency spectrum. Recently, it has been observed that, an unusual high noise and misbehavior of certain Power Electronic circuits is because of the chaotic behavior of the system, which is termed as a specific type of nonlinearity. Swilched mode DC-DC converters are the most popular power supply in Industrial products. In literature, it has been reported that the switching operations of DC-DC converters exhibit a wide range of
subhannonics and chaos, when some of the system parameters get changed. In particular, their route to chaos is charac-
