A Novel Cubic Boost Converter With Continuous Source Current for PV Applications
(Institute of Electrical and Electronics Engineers Inc., 2024) Srinivas, B.; P, P.; Nagendrappa, H.; Balasubramanian, B.
A converter with high voltage gain is generally necessary for interfacing the photovoltaic (PV) systems with grid. However, more semiconductor components are needed to obtain a higher voltage gain, which results in increased losses. This brief proposes a novel non-isolated cubic boost (NNICB) DC-DC converter for high-voltage PV applications with a wide voltage gain at a lower duty ratio. Compared to traditional high-gain DC-DC converter, the NNICB converter counters the drawbacks of increased component count and high voltage stress. The NNICB DC-DC converter has a continuous source current for PV applications with low-voltage stress across the diodes and switches. A detailed steady-state analysis of the NNICB topology is carried out for the ideal and non-ideal models, and their corresponding voltage gain equations are computed. Furthermore, the analysis is performed using MATLAB/Simulink and is validated using a 230 W laboratory prototype. The experimental results show that the efficiency of the proposed NNICB topology is 94.42% with a voltage gain of 10.5 at 45% duty ratio. This proves the superior performance of the proposed novel converter in comparison with the existing topologies. © 2004-2012 IEEE.
Fixed-frequency modified gating signals controlled high-frequency isolated LCL-T DC-DC resonant power converter
(Taylor and Francis Ltd., 2025) Reddy, V.B.; Ur Rehman, M.B.; Srinivas, B.; Nagendrappa, N.
In this paper, a fixed-frequency modified gating signals controlled LCL-T type of resonant power converter is proposed. The converter is designed to operate in lagging power factor (pf) mode to ensure zero-voltage switching (ZVS) of the inverter switches. Steady-state analysis of the converter is carried out using the Fourier series approach by considering the effect of n-harmonics. A 300 W converter is designed, and its performance is studied using PSIM simulations. It is shown that all inverter switches turn-on with ZVS for entire loading conditions with the minimum input voltage, while only one switch loses ZVS when the input voltage is maximum. Also, a small change in pulse width is enough to regulate the output voltage for wide variations in the input voltage and the load. Power loss breakdown analysis is performed. The experimental prototype of the LCL-T resonant converter is built and tested to validate the theoretical and simulation results. The results have been compared and discussed. © 2024 Informa UK Limited, trading as Taylor & Francis Group.
High Speed Data Compression Using FPGA
(Institute of Electrical and Electronics Engineers Inc., 2025) Dileep Kumar, M.J.; de Castro, G.A.; Anusha, R.; P, P.; Srinivas, B.
Efficient data compression is critical in modern digital systems to optimize storage and transmission bandwidth, especially in real-time applications. FieldProgrammable Gate Arrays (FPGAs) provide high-speed, hardware-accelerated solutions for data compression, offering parallel processing capabilities and reduced latency. This paper explores FPGA-based implementations of Run-Length Encoding (RLE) and Delta Encoding, two widely used lossless compression techniques. Performance is analyzed in terms of resource utilization, compression efficiency, power consumption, and scalability using the Xilinx Spartan-6 FPGA. Our results demonstrate that Delta Encoding achieves higher clock frequencies and lower power consumption, making it suitable for incremental data applications. In contrast, RLE excels in compressing redundant data sequences but has higher implementation complexity and variable throughput. The comparative study highlights the tradeoffs between these two methods and provides insights into their suitability for FPGA-based data compression in resourceconstrained environments. Â© 2025 IEEE.
