Mitigation of Complex Non-Linear Dynamic Effects in Multiple Output Cascaded DC-DC Converters

In the modern world of technology, cascaded DC-DC converters with multiple output configurations are contributing a dominant part in DC distribution systems and micro-grids. An individual converter any configuration exhibits complex non-linear dynamic behavior resulting instability. This paper presents system one source boost three load including buck, Cuk, Single-Ended Primary Inductance Converter (SEPIC) that analyzed for bifurcation phenomena. outer voltage feedback loop along an inner current control strategy is used all sub-converters system. To explain behavior, discrete mapping model developed proposed Jacobian matrix's eigenvalues evaluated. For simplification analysis, every regarded as fixed power (FPL) under reasonable assumptions such frequency input voltage. The period-1 period-2 reveal undergoes orbit chaos whereas operate stable orbit. eliminates chaotic from also validated using simulation MATLAB/Simulink experimental results.
