In this article, a new interconnecting modular full-bridge step-up LLC resonant converter for PV energy applications is proposed. The proposed converter module is capable of regulating power flow between modules through the use of pulse-width modulation (PWM) control on a new active voltage doubler based voltage balancer (VD), where an auxiliary switch is connected to the output VD. The input full bridge switches can be regulated with phase-shift control to achieve maximum power point tracking (MPPT) for all modules. Zero-voltage switching operation is realized on all module switches. This allows each of the converter modules to achieve a high efficiency while simultaneously achieving MPPT and balanced output voltage. The steady-state and dynamic performance of the designed system is validated on a four module 6kW, 8kV-output simulation and a scaled-down 500W, 700V-output two module laboratory prototype.

In this work, we propose a dynamical function exchange Convolutional Neural Networks (CNN) accelerator architecture named Adaptive CNN engine (ACNNE) that can reconfigure specific convolution layer hardware blocks according to model parameters at runtime. We mainly focus on exploiting reconfigurability for inferencing large-scale CNN on resource- constrained FPGAs. The proposed ACNNE can accelerate the process of convolution layers based on a nested-loop algorithm while a data buffering scheme is presented to reduce the iterations of memory accesses. As a study case, the VGG16 model was implemented on Xilinx ZU3EG MPSoC that can achieve 21.09 giga operations per second in the frequency of 100 MHz with a device resource utilization of 25% to 35%. Experiments show a single-image inference can be completed in 2.5 seconds with an average power consumption of 2.23 W, corresponding to a power efficiency of 9.46 GOPS/W.

In this study, a Recurrent Neural Network (RNN)- based PV controller is thoroughly examined and compared with conventional Incremental Conductance techniques for Maximum Power Point Tracking (MPPT). The study emphasizes the improved responsiveness and efficiency of the RNN controller and focuses on the dynamic adaptation of PV systems to changing environmental conditions. In this study, the better performance of the RNN controller in monitoring the maximum power point, its fast convergence time, and its stability under various environmental conditions are demonstrated by comprehensive simulations and comparative studies. According to the results, using cutting-edge machine learning methods, such as RNNs, may greatly increase PV systems' operational effectiveness, highlighting their potential to optimize renewable energy systems. This study offers insights that advance the realm of renewable energy technologies.
Solar irradiation fluctuations can shift the PV module's operating point away from its maximum power point (MPP). To maintain the MPP, the widely used incremental conductance (IC) method is employed as part of the...
