Bidirectional onboard chargers play a vital role in electric vehicles (Evs), contributing to smart grid applications by enabling functions such as peak load management and supporting grid stability through frequency and voltage regulation. However, traditional full-bridge dual-active bridge (FBDAB) resonant converters commonly used in these systems face considerable efficiency losses, particularly during reverse power flow and when operating away from their resonant frequency-a condition often caused by fluctuations in battery voltage. To overcome these challenges, this paper presents a bidirectional battery charger based on a CLLC resonant converter with efficient tracking mechanism. The converter's steady-state behavior is analyzed under both grid-to-vehicle (G2v) charging and vehicle-to-grid (v2G) discharging conditions. By maintaining the switching frequency close to the ideal resonant point, this design successfully lowers circulating currents in the resonant tank and transformer, decrease losses in MOSFETs, and limits the rate of current change in the diodes. Simulations comparing this approach to a FBDAB resonant converter with fixed DC demonstrate the enhanced efficiency and superior performance of the proposed system. © 2025 IEEE.

Growing III-v O-band lasers directly on patterned silicon photonics wafers has the potential to decrease the cost and increase the manufacturing throughput of integrated photonics chips needed for applications in data communications. However, this process introduces new challenges in materials growth and device design that are not present in current hybrid and heterogeneous integration techniques. In this work, we address the challenges associated with III-v growth on patterned silicon and present integrated O-band quantum dot lasers grown directly on 300 mm silicon photonics wafers. © 2025 SPIE.

optically-controlled high-voltage power devices hold good promise for grid and renewable energy applications by providing superior electromagnetic interference (EMI) immunity and reduced switching delay. This paper proposed a novel optically-controlled gate driver architecture that applies complementary optical signals to two photodiodes (PDs) arranged in a totem-pole configuration. This configuration enables fast switching of power semiconductor devices using minimal optical power, as only low-power driver signals are optically modulated and device main current is not photogenerated. To validate this approach, we employ two InGaAs PDs to drive a 3.3 kv SiC MOSFET, the highest-voltage industrial unipolar device currently available. When each PD is illuminated by 21.7 mW optical power, the SiC MOSFET achieves hard-switching at 1500v/3A, with rise and fall times of 152 ns and 214 ns, respectively. These results set new records for switching voltage, speed, and power capacity-to-optical power ratio in optically-controlled unipolar power switches. This general optical driver design is also applicable to the future development of integrated optics for power electronics in diverse (ultra-) wide-bandgap semiconductors.1 © 2025 IEEE.

The penetration of conventional energy sources is decreasing while energy demand is increasing. Therefore, alternative energy sources are required to ensure an emission-free environment and to meet energy demands, such as photovoltaic (Pv) systems. The generating voltage of a Pv source is low, so high-voltage gain converters have been developed to meet the required load demands. This article presents a grid-connected Pv system using a high-gain converter. The high-gain converter in the proposed system offers several advantages, such as fewer components, design with a single switch, minimal gate driver circuitry, low cost, and high efficiency. The Pv source voltage acts as the input to this high-gain converter. The bidirectional DC/AC converter is controlled by hysteresis current control. The active component current for hysteresis current control is generated using the loss component current, load power, and Pv power. The aforementioned control strategy maintains power management between the electrical sources and the load. The suggested system is simulated for a 1.2 kW power rating, and the obtained simulation results are presented.

We introduce the DODAG-X protocol for multipartite entanglement distribution in quantum networks. Leveraging the power of Destination Oriented Directed Acyclic Graphs (DODAGs), our protocol optimizes resource consumption and enhances robustness to noise in dynamic and lossy networks. Implementing a variation on the X-protocol within the DODAG, we minimize graph verification and path-finding calculations, significantly reducing computational overhead when compared to other entanglement routing schemes. Additionally, our benchmarks on grid lattice and small-world topologies reveal substantial measurement reduction compared to existing protocols. We demonstrate the success of DODAG-X for generating maximal three-party entanglement in arbitrary networks, and describe the potential for scaling to generic n-party entanglement. The DODAG-X protocol provides a scalable and efficient solution for entanglement routing, advancing current techniques for reliable quantum communication and network applications. © 2025 SPIE.

Microinverters are typically integrated with individual solar photovoltaic (Pv) modules to enhance system performance. This paper presents the design and evaluation of an interleaved flyback DC-DC converter for microinverters in a methodical approach. The flyback converter is selected for its advantages, including a reduced component count and a simplified architecture. Additionally, it provides electrical isolation, meeting grid code requirements, and offers high voltage gain, making it suitable for a wide range of input voltages. The time-interleaved operation of the DC-DC flyback stage, utilizing multiple parallel switching phases, effectively reduces ripple current, minimizes component stress, and improves power density. An active clamp circuit is incorporated to recover leakage energy. The operational principles, including all modes of operation, are thoroughly explained. The complete design is presented with relevant mathematical formulations and validated through software simulations.

The voltage-fed quasi Z-source inverter (qZSI) is emerged as a promising solution for photovoltaic (Pv) applications. This paper proposes a novel high-gain partition input union output dual impedance quasi Z-source inverter (PUDL-qZSI) for Pv grid-connected system. This advanced inverter design achieves exceptionally low shoot-through duty ratios and high modulation index, resulting in a superior output current with reduced total harmonic distortion (THD). To modulate three-phase qZSIs and other equivalent topologies, a variety of modulation schemes may be used, some of which involve two extra reference signals to generate shoot-through state. The simulation is carried out on the MATLAB/Simulink environment with Pv-based grid-connected PUDL-qZSI to measure the harmonic distortion and power measurement. The proposed inverter is subjected to two different pulse width modulation (PWM) analysis are simulated and compared to validate the proposed system. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Metasurfaces have been widely investigated across the disciplines of optical biosensing due to their exceptional ability to manipulate electromagnetic fields. Consequently, over the past few years, there has been growing interest in the application of metasurfaces in optical biosensors in the field of biomedical sensing. While being label-free and offering real-time tracking, high sensitivity, and a quick response are among the benefits of conventional optical biosensors, the incorporation of metasurfaces improves their wavefront manipulation, selectivity for versatile sensing, and capacity for device miniaturization to satisfy increasingly complex application requirements. Furthermore, there is a lack of comprehensive evaluations that address the current research developments and future possibilities, despite the encouraging advancements in this emerging field. Hence, this work provides a comprehensive review and serves as a valuable resource for researchers exploring metasurface-based optical biosensors. This review delves into defining the basic sensing concepts, design procedures, and important figures of merit (FOM) for metasurface-based optical biosensors and their applications, including the detection of numerous analytes, such as viruses, toxins, antibodies, tumors, and drugs and the monitoring of blood sugar. Furthermore, presenting a critical evaluation of structural fabrication techniques with a view toward potential future commercialization, this review ends by highlighting several fascinating areas for further investigation. For this review article, a total of 5844 effective documents about metasurface optical biosensors were retrieved from the Scopus database. The vOSviewer version 1.6.20 bibliometric software was used for the scientific analysis of the data retrieved from the Scopus database from 2010 to 2025. © 2025 by the authors.
