The proposed structure is built around four square ring resonators, which are meticulously etched onto the top surface of an RO4003C substrate. This particular substrate is widely recognized for its reliable performance in high-frequency circuits due to its specific electromagnetic properties, including a permittivity of 3.55 and a low loss tangent of 0.0021. These characteristics are crucial for ensuring minimal signal loss and maintaining efficient filtering at RF frequencies. The physical configuration of the circuit was carefully optimized, resulting in overall dimensions of 61.1358 mm in length and 48.233 mm in width. The compactness of the design makes it suitable for integration into modern communication systems where space and performance are at a premium. In terms of structural design, the bandpass filter employs a single-layer configuration, which houses the four resonators. This streamlined architecture simplifies fabrication while maintaining the necessary functionality and performance. A key feature of the design is the integration of nine varactor diodes, which are carefully placed to enable reconfigurability. These diodes allow for fine-tuning of the resonant frequencies by dynamically adjusting the capacitance values, which in turn alters the filter's operational frequency band. The ability to reconfigure the filter's response on demand is highly advantageous, particularly in communication systems that need to operate over multiple frequency bands or adapt to varying conditions. To ensure the validity of the design, extensive simulations were conducted using the Advanced Design System ADS solver, a reliable tool for RF circuit analysis. The simulation results confirmed the effective performance of the filter, demonstrating not only its strong filtering capabilities but also the smooth reconfigurability achieved through the integration of the varactor diodes. The flexibility provided by this reconfigurable nature makes the filter a promising candidate for advanced communication systems, especially those requiring adaptive filtering to support the transmission and reception of signals across multiple frequency bands. This design represents a significant advancement in filter technology, with potential applications in next-generation communication systems that prioritize flexibility, adaptability, and performance.</div></div>","PeriodicalId":100488,"journal":{"name":"e-Prime - Advances in Electrical Engineering, Electronics and Energy","volume":"11 ","pages":"Article 100889"},"PeriodicalIF":0.0,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143177083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The majority of active-controlled AC/DC converters are built using the boost converter technique. This technique offers a high input Power Factor (PF), which lowers total harmonic distortion and circuit power losses while increasing conversion efficiency. The objective of the research was to investigate the optimal methods for designing and producing PFCs with high power densities and to assess the effectiveness of both topologies through simulation and experimental testing. The work focuses on designing and controlling high-power density converters with power factor correction using multilevel rectifiers. It aims to enhance efficiency, reduce harmonic distortion, improve power quality, and optimize performance in high-power applications through advanced converter topologies and control strategies. In classic boost converter-based PFC systems, the input filter inductor of the boost converter's size and the bank of twice-line frequency energy buffering capacitors (TLFEB) are two of the main obstacles to obtaining high power density. Accordingly, the article suggested multilevel inverters for high power density. Initially, the study proposed the three-phase dual boost five-level rectifier to improve core coupled inductors. The paper also introduces a six-level Flying Capacitor Multilevel (FCML) boost converter-based Power Factor Correction (PFC) front end. Due to the FCML converter's unique properties, the filter inductor's size may be drastically reduced while keeping high efficiency, thus enhancing the PFC front end's power density. By using a single-phase cascaded H-bridge inverter to optimise the boost converter voltage and current parameters, the performance of both PFC topologies was examined. The combination of high-energy-density ceramic capacitors and a single-phase cascaded H-bridge seven-level inverter converter can significantly enhance the performance of the three-phase rectifier. The multilevel converter's dynamics have been analysed and implemented using Matlab software. For universal AC input, 1.5 kW power rating, and 400-V DC output, a hardware prototype is created.

Electromagnetic control devices offer superior performance indicators compared to traditional mechanical force actuators in terms of longevity, energy efficiency, maintenance requirements, rapid control response, and high operating speeds. This article investigates the use of magnetic actuation and switching power electronics in addressing the stabilization and tracking control challenges encountered in the dynamics of a mechanical system with a single degree of freedom, comprising mass, spring, and damper elements. Particularly, a linear mechanical oscillator is nonlinearly coupled with an electromagnet and its associated driving circuit via the magnetic field. The electromagnetically actuated mechanical system exhibits characteristics of a deferentially flat nonlinear system. A control strategy is suggested for the purpose of tracking reference position trajectories using output feedback linearization. The synthetic linearized control signal is subsequently guided to a DC–DC buck converter, able to regulate the system’s input voltage in a wide range of operation, by switching the duty cycle. The converter is described using a precise electrical model of the system, accounting for parasitic resistances in the inductor, capacitor, and switches. An averaged state space approach is utilized to create a mathematical nonlinear model for the converter which is then linearized by employing the Exact Feedback Linearization technique. By applying optimal control theory, the controller’s coefficients are fine-tuned for optimal performance. To assess the proposed method’s performance, the dynamics of the compensated mechatronic system is simulated using MATLAB/Simulink. The simulation results demonstrate that the proposed control scheme choice for active control of vibrating mechanical systems using magnetic coupling and switching DC–DC converters meets the requirements and specifications.
