Implementation and reliability analysis of a new non‐isolated quadratic buck–boost converter using improved Markov modelling

Here, a new buck–boost converter with reliability analysis is proposed. The has utilized voltage multiplier cell at the input side to boost output voltage. It continuous current wide range of duty cycle operations. achieves unity gain 26.8% and can also operate in discontinuous conduction modes buck modes. detailed proposed using improved Markov modelling presented by considering both open circuit short faults across semiconductor devices. variation mean time failure (MTTF) different parameters like discussed here. hardware results developed prototype are here varying ratios. power loss comparison other newly topologies show advantages converter. For checking stability converter, state space model detail
