With the rapid development of new energy and the energy-saving technology, three-level inverter has gradually become the core of power conversion because of its large output capacity, good dynamic performance, low harmonic content and high inversion efficiency. In the view of the inherent problem of uneven DC side voltage distribution in T type three-level inverter, this paper analyzes the influence factors of neutral point potential imbalance based on SVPWM (Space Vector Pulse width Modulation method), and establishes the midpoint average current mathematical model. According to the current state of the midpoint under different types of vector action, a self-adaptive distribution factor method is proposed, which can self-adjust according to the potential difference of the midpoint, and the expected effect is obtained in the simulation.
随着新能源和节能技术的快速发展,三电平逆变器因其输出容量大、动态性能好、谐波含量低、逆变效率高等优点,逐渐成为电力转换的核心。针对T型三电平逆变器直流侧电压分布不均匀的固有问题,本文基于空间矢量脉宽调制方法(SVPWM)分析了中点电位不平衡的影响因素,建立了中点平均电流数学模型。根据中点在不同类型矢量作用下的当前状态,提出了一种自适应分布因子方法,该方法可以根据中点的电位差进行自调整,并在仿真中获得了预期的效果。

A 14-bit 500-MS/s SHA-less pipelined Analog-to-Digital Converter (ADC) for receiver application is fabricated on a 65 nm CMOS relying on correlation-based background calibrations to correct the inter-stage gain and settling errors. In order to suppress the non-linearity caused by inter-stage gain error due to insufficient amplifier gain, a new dithering technique is employed on the residual transfer function. In addition, the comparators in all stages are trimmed digitally to minimize their offset and further improve the linearity. The measured signal-to-noise ratio (SNR) and spurious free dynamic range (SFDR) are 67 dB and 88 dB after calibration at 350 MHz input signal. The ADC occupies an active area of 3 mm2 and consumes a total power of 0.9 W from 1.3 V and 2.0 V supplies.
基于基于相关的背景校准来校正级间增益和定位误差,在65nm CMOS上制作了用于接收器应用的14位500 ms /s无sha的流水线模数转换器(ADC)。为了抑制由于放大器增益不足而引起的级间增益误差引起的非线性,在残差传递函数上采用了一种新的抖动技术。此外,所有阶段的比较器都以数字方式修剪,以尽量减少其偏移,并进一步提高线性度。在350 MHz输入信号下校准后,测量到的信噪比(SNR)和无杂散动态范围(SFDR)分别为67 dB和88 dB。ADC的有效面积为3mm2, 1.3 V和2.0 V电源的总功耗为0.9 W。

Proof-of-work, as the core technology of public blockchain, requires users to pay a certain amount of work in order to create new blocks by competition. This article innovatively applies it to the train ticket market, and introduces such a mechanism at the interface of the ticketing system to prevent the system from being attacked. Based on the background of China's internet train ticketing system, this paper analyzes the internal and external attacks on the system, designs an algorithm based on proof-of-work, and expands according to the geographical location, credit rating, and system load based on different problems. However, there is a big difference in CPU performance between different computer devices, leading to the difficulty for some users with insufficient computing power to buy tickets. The time difference in accessing the memory has the same algorithm complexity. Therefore, the algorithm that was previously limited to the CPU needs to be adjusted to Memory-bound algorithms. The results show that the application of memory-bound proof-of-work algorithm in the ticket purchasing market can better balance the difficulty of buying tickets and resist external attacks, so as to satisfy most people's ticket requirements and ease the pressure of Spring Festival travel.
工作量证明作为公链的核心技术,需要用户付出一定的工作量,通过竞争创造新的区块。本文创新性地将其应用于火车票市场,并在票务系统的接口引入这样的机制,防止系统被攻击。本文以中国互联网火车票售票系统为背景,分析了系统受到的内部攻击和外部攻击,设计了基于工作量证明的算法,并根据不同的问题根据地理位置、信用等级和系统负载进行扩展。然而,不同计算机设备之间的CPU性能差异较大,导致一些计算能力不足的用户难以购买门票。访问内存的时间差具有相同的算法复杂度。因此,以前仅限于CPU的算法需要调整为内存绑定算法。结果表明,在购票市场中应用内存绑定工作量证明算法,可以更好地平衡购票难度和抵御外部攻击,从而满足大多数人的购票需求,缓解春运压力。

In this paper, a novel control strategy using the line voltage information to realize the space vector pulse width modulation (SVPWM) is proposed. The principles and implementation steps of SVPWM are given. In the algorithm flow, the phase angle $boldsymbol{theta}$ of phase voltage is the most important input information for SVPWM strategy. For the three phase system, the phase angle $boldsymbol{theta}$ can't be detected directly. This paper shows the derivation process of line voltage to phase voltage for the three phase three wire system. According to the intrinsic relationship of the line voltage and the phase voltage, the three phase three wire inverter prototype is produced to validate the SVPWM control strategy. It makes the three phase system use the SVPWM reliably and easily. The experimental results are shown. It validate the new control strategy using the line voltage information to realize the SVPWM.

Due to the special application, noise and power consumption optimization method is introduced from structure level to device level. For structure level, the capacitance proportional circuit is carefully designed to achieve a closed-loop gain and band-pass filtering function at the same time. The adoption of Sub-threshold MOSFETs obtains low noise and high resistance in device level.

A Queue Manager Support Independent Management of Multicast Queues for CIOQ Switches 队列管理器支持独立管理CIOQ交换机的组播队列

Traditional ways to manage the multicast queues in the queue manager are simple and easy to implement, but with the development of the Internet, the demand for the bandwidth increases rapidly and the problem of these schemes in resources and throughput becomes more serious. In this paper, we analyze three different schemes used for the multicast queues and design a queue manager for CIOQ switches, which can support independent management of multicast queues. The queue manager designed separates unicast queues and multicast queues, thus can provide different QoS (quality of service) for these two queues, and then allocate bandwidth more flexibly. In addition, we use link list instead of independent FIFO in the design in order to save resources. Moreover, the throughput of the system will be improved due to the controlled traffic. The whole design is realized with Verilog HDL, simulated with Modelsim SE 10.2c in Xilinx xc6vlx240t FPGA. The simulation result shows the design can implement the functions we need and useful to meet the requirements of resources, efficiency and throughput, hence the design is valuable.
传统的在队列管理器中管理组播队列的方法简单、易于实现,但随着互联网的发展,对带宽的需求迅速增加,这些方案在资源和吞吐量方面的问题日益严重。本文分析了三种不同的组播队列管理方案,设计了一种用于CIOQ交换机的队列管理器,实现了对组播队列的独立管理。设计的队列管理器将单播队列和组播队列分开,可以为这两个队列提供不同的QoS(服务质量),从而更灵活地分配带宽。此外,为了节省资源,我们在设计中使用链表而不是独立的FIFO。此外,由于对流量的控制,系统的吞吐量将得到提高。整个设计用Verilog HDL实现,在Xilinx xc6vlx240t FPGA上用Modelsim SE 10.2c进行仿真。仿真结果表明,该设计能够实现我们需要的功能,能够满足资源、效率和吞吐量的要求,具有一定的设计价值。

In this paper, we analyze three different schemes used for the multicast queues and design a queue manager for CIOQ switches, which can support independent management of multicast queues. The queue manager designed separates unicast queues and multicast queues, thus can provide different QoS (quality of service) for these two queues, and then allocate bandwidth more flexibly. In addition, we use link list instead of independent FIFO in the design in order to save resources. Moreover, the throughput of the system will be improved due to the controlled traffic. The whole design is realized with Verilog HDL, simulated with Modelsim SE 10.2c in Xilinx xc6vlx240t FPGA.
