“…A single-path hybrid step-down converter has been realised, by dividing the input DC-link, using a switched capacitor network, and connecting buck converters across the capacitors. The buck converters are controlled as interleaved units in [78]. This approach is more useful when designing the power stage of portable systems.…”

Voltage step-down converters have gained attention, with the rapid development in industrial robotics, Internet of things, and embedded system applications. Therefore, a comprehensive analysis has been performed, to identify the topologies and architectures used in step-down converters. Moreover, their operation and performance have been compared. Such an analysis is helpful, in improving performance of the existing systems, besides designing novel converter topologies. Furthermore, the converter-topology-derivation methods have been studied, to identify their applicability for synthesising novel non-isolated DC–DC converters.

“…A system diagram as shown in Fig 6, where one of the inputs is connected to the output of the PV array and other inputs is connected to the output of the generator output. The fusion of the two converters is achieved by reconfiguring the two existing diodes from each converter and the shared utilization of the cuk [10] [11], [12], [13] output inductor by the sepic converter [11], [13], [14] together become a proposed rectifier stage of the hybrid energy system [13], [15], [16], [17]. This configuration allows each converter to operate normally individually in the event that one source is unavailable.…”

The aim of this study is to introduce the local PV-wind hybrid system's working principle by reviewing one case where the system is connected to the grid. The thermal power stations are causing pollution which severely affects mankind and nature. These power stations result in causing many diseases. Also natural resources like coal, oil,radioactive materials etc will get extinct in near future. The other existing power generating systems like Hydro-Electricity power generating plant cannot afford much power as it is season based, although it causes less pollution. Therefore, it is of great urgency to go for non conventional energy resources. In recent years, environmental friendly technological solutions are becoming more prominent as a result of concern over the state of our deteriorating planet. The main purpose of this hybrid wind-solar energy system is to meet our daily demand effectively and to get an uninterrupted power supply from any one of the natural source either wind or solar or both. The hybrid model is designed using Cuk-SEPIC fused convertors and the performances are analyzed. Due to the inherent nature of this Cuk-SEPIC fused convertors, we get optimum efficiency Simulation results are given to highlight the merits of the proposed circuit. To ful fill the challenging demands of the growing grid, new concepts of the inverters are needed. Inthis project a reduced switch modular inverter design is detailed. A modular inverter design is presented for a modern power system which inputs power from both AC andDC Renewable Sources.

“…Energy-saving and carbon reduction have become the primary development goals for each country. The demand for relevant regulations (e.g., the Energy Star Standard and California Energy Commission Appliance Efficiency Regulations) and the market in recent years have driven the continual development of high-efficiency and high-power-intensity power supply units [1,2]. Because wide-bandgap materials are characterized by high breakdown voltage and high electron mobility, which merit operation under high temperatures and high frequencies [3][4][5][6][7][8][9][10], they have enabled the development of power supply units to gradually transition from silicon power switches to wide-bandgap power switches [3][4][5].…”

An enhancement-mode gallium-nitride high-electron-mobility transistor (E-mode GaN HEMT) operated at high frequency is highly prone to current spikes (di/dt) and voltage spikes (dv/dt) in the parasitic inductor of its circuit, resulting in damage to the power switch. To highlight the phenomena of di/dt and dv/dt, this study connected the drain, source, and gate terminals in series with inductors (LD, LS, and LG, respectively). The objective was to explore the effects of di/dt and dv/dt phenomena and operating frequency (fS) on drain-to-source voltage (Vds), drain-to-source current (Ids), and gate-to-source voltage (Vgs). The experimental method comprised two projects: (1) establishment of a measurement system to assess the change of electrical characteristics of the E-mode GaN HEMT and (2) change of the fS and the inductances (i.e., LD, LS, and LG) in the circuit to measure the changes in Vds, Ids, and Vgs, thus summarizing the experimental results. According to the experimental results on electrical characteristics, a gate driver circuit may be designed to drive and protect the E-mode GaN HEMT while being actually applied to a 120-W synchronous buck converter with an output voltage of 12 V and an output current of 10 A.
