“…There are three modes converter is implemented in MATLAB. The performance analysis of proposed IBI-SW framework based PWM is compared with the existing Interleaved Boost Power Factor Correction (IB-PFC) [1] and Quantification of Interleaved Power Factor Correction (QI-PFC) [2]. The feasible study of the system is performed by experimenting through the metrics such as power output, ripple effect, switching time, switching noise and converter efficiency with voltage and current settings.…”

“…Thus the proposed IBI-SW based PWM framework reduces the ripple effect for dc-dc converter than the other two state-of-the-art methods. This is because with the integration of soft switched Bayes interleaving and sliding window based PWM, switching transition is made in an efficient manner in IBI-SW framework that helps to track the maximum power point using variable gain and therefore decreases the ripple effect by 6% and 14% when compared to IB-PFC [1] and QI-PFC [2] respectively.…”

“…A large number of training data for different IBI-SW based PWM framework were generated using MATLAB software, taking into account various scenarios at different time and different input voltages, ranging between 10V and 70V. In fig.8, the switching time is symbolized using the framework IBI-SW and compared with two other methods IB-PFC [1] and QI-PFC [2]. The switching time was observed under conditions with respect to different power output.…”

In order to develop the efficient dc-dc boost converter in high output power application, an Integrated Bayes Interleaved and Sliding Window (IBI-SW) based PWM framework is proposed. Initially, the integration of interleaving and PWM improves the power factor correction in very high output power applications (photovoltaic panels) and near optimal voltage and current losses. Multiple phase shifts with soft switched Bayes interleaving technique maximizes the power generated in photovoltaic panels and the optimization of power conversion is achieved with sliding window based PWM that performs Maximum Power Point Tracking (MPPT) algorithm on the PV cells connected to the converter. The proposed dc-dc boost converter is efficiently tested on various load conditions for measuring the scalability of IBI-SW framework in multiple high power demanded application. When compared with traditional model, the simulation result of proposed IBI-SW based PWM framework demonstrates that the dc-dc converter improves the power generated in photovoltaic panels accurately and rapidly.
