Dual Side Control Design for a 600w Lcc Compensated Wireless Power Transfer System
(Institute of Electrical and Electronics Engineers Inc., 2022) Pashaei, A.; Aydemir, Mehmet Timur; Aydin, E.; Aydemir, M.T.
The purpose of this paper is to design a dual side control for a 600 W LCC resonant WPT electrical bicycle with an 85 kHz resonant frequency. Primary side control use inverter voltage and current to determine mutual inductance and load value in coils misalignment case. The secondary side control uses a DC-DC converter that has two voltage and current feedback with a PI controller to achieve CC/CV charging in the battery. Additionally, with primary side control the high-frequency inverter operates in ZVS mode. Optimal design parameters are obtained and results and control method feasibility validated by simulations. © 2022 IEEE.

(Springer, 2025) Zohaib, M.; Navimipour, N.J.; Aydemir, M.T.; Ahmadpour, S.-S.
Signal processing had a significant impact on the development of many elements of modern life, including telecommunications, education, healthcare, industry, and security. The semiconductor industry is the primary driver of signal processing innovation, producing ever-more sophisticated electronic devices and circuits in response to global demand. In addition, the central processing unit (CPU) is described as the “brain” of a computer or all electronic devices and signal processing. CPU is a critical electronic device that includes vital components such as memory, multiplier, adder, etc. Also, one of the essential components of the CPU is the arithmetic and logic unit (ALU), which executes the arithmetic and logical operations within all types of CPU operations, such as addition, multiplication, and subtraction. However, delay, occupied areas, and energy consumption are essential parameters in ALU circuits. Since the recent ALU designs experienced problems like high delay, high occupied area, and high energy consumption, implementing electronic circuits based on new technology can significantly boost the performance of entire signal processing devices, including microcontrollers, microprocessors, and printed devices, with high-speed and low occupied space. Quantum dot cellular automata (QCA) is an effective technology for implementing all electronic circuits and signal processing applications to solve these shortcomings. It is a transistor-less nanotechnology being explored as a successor to established technologies like CMOS and VLSI due to its ultra-low power dissipation, high device density, fast operating speed in THz, and reduced circuit complexity. This research proposes a ground-breaking ALU that upgrades electrical devices such as microcontrollers by applying cutting-edge QCA nanotechnology. The primary goal is to offer a novel ALU architecture that fully utilizes the potential of QCA nanotechnology. Using a new and efficient approach, the fundamental gates are skillfully utilized with a coplanar layout based on a single cell not rotated. Furthermore, this work presents an enhanced 1-bit and 2-bit arithmetic logic unit in quantum dot cellular automata. The recommended design includes logic, arithmetic operations, full adder (FA) design, and multiplexers. Using the powerful simulation tools QCADesigner, all proposed designs are evaluated and verified. The simulation outcomes indicates that the suggested ALU has 42.48 and 64.28% improvements concerning cell count and total occupied area in comparison to the best earlier single-layer and multi-layer designs. © The Author(s) 2025.
