Summary: This article introduces a compact five-level common-ground-type inverter with inherent boosting capability for solar photovoltaic applications. The inverter utilizes two switched capacitors rated for only half of the output voltage with self-voltage balancing ability, reducing size, cost, and complexity. Compared to other inverters, it has lower component count, total standing voltage, dv/dt, number of conducting devices, and capacitor voltage diversity factor.

Summary: This study explores the potential applications of photoactive polymer dots in energy conservation and renewable fuel industry, and proposes their innovative use in photomemory applications for the first time. The research reveals that the photomemory characteristics can be simply tuned by changing the core conjugated structures of Pdots, and inserting Pt complexes into polymer backbones to form cycloplatinated Pdots can convert the storage type of derived devices from volatile memory to nonvolatile flash memory.

Summary: Two new types of floating gates composed of pn-type polysilicon or np-type polysilicon have been developed in this study to lower charge leakage and improve the operation performance of memory devices. By forming an n-p junction in the floating gate, the sheet resistance is increased and charge leakage is reduced, leading to improved performance without the need for new materials or changes to the physical structure.

Summary: We investigate the collective coupling between atoms and an optical cavity mode with multilevel ground-state manifolds experimentally and theoretically. The cavity field optically pumps populations among the ground states in our setup. The resulting dynamics can be described conveniently by an effective dynamical atom-cavity coupling strength that relies on the occupation of individual states and their coupling strengths with the cavity mode. This leads to a nonexponential relaxation dynamics due to the dynamical backaction of the atomic populations on the atom-cavity coupling strength. We experimentally observe this effect with laser-cooled 87Rb atoms and monitor the collective normal-mode splitting in real time. Our results demonstrate that the multilevel structure of electronic ground states can significantly alter the relaxation behavior in atom-cavity setups compared to ensembles of two-level atoms.

Summary: The article discusses a nine-level switching capacitor-based boost inverter for grid-connected photovoltaic applications. The proposed structure eliminates leakage current by directly connecting the input source's negative terminal to the grid neutral. The inverter uses eleven switches, two diodes, and three switching capacitors to achieve a double voltage boost with nine different voltage levels. Experimental findings demonstrate the high performance of the proposed topology.

Summary: This article presents a solution to mitigate leakage-ground currents in a grid-tied H-bridge neutral-point clamped inverter by splitting the LC filter capacitor and connecting each capacitor to a dc-link terminal. The proposed method does not require increasing the number of switches or designing a new modulation scheme. Formal analysis and experimental tests show that this method effectively reduces leakage-ground currents.

Summary: This article develops a semianalytical model to characterize the terminal responses of coated floating-ground multiconductor cables (FMCs) under nonuniform electromagnetic field. The proposed method decomposes the field-to-wire coupling effects in coated FMCs into common-mode and differential-mode coupling and derives a combination model based on transmission line theory. The method is validated through application examples and shows good accuracy and computational efficiency compared with full-wave simulations.
