This paper presents a novel compact balun combiner based on lumped inductors and capacitors. In addition to the functions of harmonic reducing, power combining, and impedance matching, the new structure accomplishes both the 2(nd) and the 3(rd) harmonic suppression by constructing band-stop filters and cancellation pathways. The proposed topology is studied theoretically and demonstrated on an FR4 printed circuit board with the size of 2 cmx4 cm. Experiment results show that differential power combination is achieved with around 0.7-dB loss for each path when all three ports are loaded to 50 ohms at 1 GHz. The 2(nd) harmonic suppression is more than 28-dB at 2 GHz and the 3(rd) harmonic can be largely canceled out with equal amplitudes while opposite phase at 3 GHz. Furthermore, the topology can be applied in not only printed circuit boards but also monolithic microwave integrated circuits.

Boost converters are vital in various power electronics applications including power supplies, battery charging circuits, LED drivers, and renewable energy systems. They efficiently step up low voltage inputs to higher voltage outputs, making them indispensable across diverse industries. This paper offers a thorough exploration of the boost converter circuit, detailing the development of its small-signal state space model and transfer function. To control the circuit, pole placement, linear quadratic regulator (LQR), PI controller, active disturbance rejection control (ADRC) techniques are employed. The resulting step responses of each controller are compared. Analysis and simulation results demonstrate that the LQR is the most effective controller in achieving the desired step response by reducing settling time and overshoot. This study offers valuable insights for designing and controlling boost converter circuits in practical applications.

This paper presents a high-precision and low-power two-stage miller-compensated instrumentation amplifier for sensor readout circuits. Folded-cascode structure with complementary input differential pairs and translinear-loop-based class AB circuit are adopted as the amplifier first and second stages respectively, to achieve rail-to-rail input and output ranges. The presented instrumentation amplifier is implemented in a 0.18 mu m BCD technology. Measurement results show that with a load of 100pF and 100k Omega, the presented amplifier achieves 79.79dB gain, 1.35MHz gain-bandwidth product (GBW) and 92.3dB power supply rejection ratio (PSRR). The measured amplifier gain error is 0.11%;and its input offset voltage is 0.3mV. This amplifier totally consumes 0.19mW power from a 3V supply voltage.

Battery management system (BMS) includes the main functions of state estimation, safety protection, parameter testing and information management. The most core function of BMS is to estimate state-of-charge (SOC). Prerequisite for BMS to be able to accurately perform SOC estimation is to have a model with high accuracy. In this paper, the impedance spectral characteristics of each SOC point of lithium-sulfur batteries (LiSBs) are tested. First-order resistor-capacitance (RC) equivalent circuit model (ECM) and second-order RC ECM are both established. The experimental data are used to identify the parameters of the model and complete the modeling. MATLAB/Simulink is used to build a simulation platform to complete the simulation verification of LiSBs constant current discharge condition. The simulation results show that the maximum simulation error of the first-order RC ECM is about 3%, and the average value of the errors in the total interval is 19.8 mV. The simulation error of the 2nd-order ECM is 0.9% with an average value of the error in the total interval of 4.3 mV. The 2nd-order ECM fits the actual discharge condition of LiSBs more accurately. The research results of this paper can provide technical support for the development of energy storage systems for green airports. © 2024 IEEE.

Field Programmable Gate Array (FPGA) circuits have become an integral part of recent embedded process control designs. However, printed circuit board (PCB) layout design has become increasingly challenging due to the various propagation delays associated with FPGA pin count. To compensate for these delays on the PCB side, high-speed PCB interconnect lines are left unmatched, making sign-off of the board a major challenge in the absence of an FPGA model. Unfortunately, FPGA vendors do not provide the behavior model of FPGA;instead, they give only the pin delay report in a comma-separated file format. This file format is not considered by most simulation tools during analysis and simulation, thus limiting signal data rates to 10 Gbps for board-level simulation. Timing violations arise in simulation results if the duration of these signals differs at the board level at these high data rates, and as a result, the board must be redrawn. This paper presents a novel methodology for creating FPGA models that incorporate package delay in the absence of accurate package models on the board, known as package co-simulation. A close-to-actual parametric spice model of the package is generated, which is tested on a high-speed FPGA board. The simulation results of the proposed package model are compared to the absence of the package model results, indicating that the interconnect delay inside the package is considered during board package *** methodology is a significant advancement in the field of FPGA circuit design, as it enables designers to create more accurate models of FPGA circuits and optimize PCB layout design while considering the propagation delays and package interconnect delays. It is expected that this methodology will be a valuable tool for future FPGA circuit designs, enabling designers to achieve a higher level of accuracy and efficiency. © 2024 IEEE.

The high-precision fault diagnosis management method in multi-mode control systems was studied. Three typical power conversion circuits were selected to use full convolutional network (FCN), residual network (RESNET) and self-attention network (TRANSFORMER) for fault diagnosis algorithm research, and a fault diagnosis management method verification platform was built based on this. The algorithm model was built using Python in the Pytorch environment on a computer with 16GB RAM and a 3060 graphics card. The switching power supply circuit based on Tps53355 was analyzed by Pspice sensitivity, and 6 devices with the greatest impact on the output were obtained. The Adam optimizer was used, the total number of epochs trained was 60, and the mini-batch size was fixed to 64. The simulation verification showed that this model can achieve the system engineering management requirements: the fault detection accuracy is not less than 91%, the false alarm rate of lightweight power warning is not higher than 1.05%, and under multiple faults, no less than 3 composite faults can be identified. © 2024 IEEE.

The current modeling techniques of a Double-fed induction generator (DFIG) for wind power systems have shortcomings in the idealization of equipment internal parameters and unitization of system coupling. In this paper, a multi-model fusion method of doubly-fed induction wind turbine modeling for wind power systems is proposed. Firstly, the 1.5 MW DFIG body is constructed according to the parameters of the physical prototype. Then, to realize the system's control of DFIG, the DIFG external circuit and control circuit of the wind power system are built to realize multi-system coupling simulation modeling. Through simulation analysis, the effectiveness of the multi-model coupling simulation system and the availability of the method are proved. © Published under licence by IOP Publishing Ltd.

The circuit breaker closing and energy storage is an important technical guarantee in the structure of the rail transit power supply system. Its function is to absorb excess energy in the feedback loop from the train to the rectifier system. Traditional circuit breakers closing rely on DC motor tension springs for energy storage-significant energy loss in DC control circuits and equipment's internal components. Firstly, analyze the characteristics and curve operation rules of the flywheel energy storage array (FESA). Secondly, the flywheel energy storage array is applied in the dynamic monitoring method of circuit breakers for the recovery of regenerative energy during train braking, It has important implications for meeting energy conservation and voltage regulation requirements. Finally, a magnetic field model is established through the cyclic parameter changes of permanent magnet synchronous motor (PMSM), experimental evidence shows that flywheel energy storage arrays are more energy-efficient than battery packs or super capacitors in subway systems. It has high instantaneous power, high energy storage density, and slow operational response attenuation, convenient management of state of charge, and balanced charging and discharging.
