چکیده
In this paper, a comparative analysis on the bifurcative and chaotic behaviour of a current controlled buckboost converter with soft switching and hard switching is performed. The electromagnetic interference generated during hard switching and soft switching of the converter is analyzed. Simulation and measured results show that the total energy is more evenly spread over the frequency band during soft switching with reduced power loss. It is also found that the reduction of EMI and efficient performance of the dcdc buckboost converter with soft switching is comparatively better than the hard switching.
