The non-isolated bidirectional DC-DC converters are the most popular topology for low or medium power of the hybrid electric vehicle (HEV) or fuel cell vehicle (FCV) applications. These kinds of converters have the advantages of simple circuit topology, bidirectional flows, zero-voltage-switching (ZVS), high efficiency, and high power density. The turned-on ZVS for all MOSFETs is achieved by the negative offset of the inductor current at the beginning and the end of each switching period. To do this, the converter requires a complex switching strategy which is preferred to be implemented by the digital signal processing (DSP). This paper presents the digital implementation of the switching pattern to ensure the ZVS condition for such converter. A 5kW prototype is performed to verify the capability of such control scheme.

Narrowband internet-of things (NB-IoT) is a 3GPP standard designed for Internet-of-Things (IoT) application. This paper presents the design consideration and possible options of a UE-specific uplink (UL) scheduler for NB-IoT system. We developed a unitary C emulation platform to verify the effectiveness of the proposed approaches, which is currently under integration within the OpenAirInterface NB-IoT project.

Due to the limitation of vehicle space, more and more modular were integrated together, such as DC/DC and AC/DC charger were integrated in the distribution. In order to overcome excessive volume and confused layout of modular, a new multifunctional vehicle distribution box was design. The internal modules of the distribution box would affect each other and the temperature field. A few of design and improve rules were presented together with temperature field simulation. The simulation result by ANSYS showed the improvement would effectively reduce the temperature of the distribution box.

The high-power laser diode driver (HPLDD) that combines the buck-boost converter (BBC) and feedback controllers was designed and implemented for the vehicle headlights. The buck-boost converter could be operated in all conversion modes including step-up, step-down, and step-up-down, with variable battery voltages input to the HPLDD. Moreover, the feedback controllers composed of a voltage-loop controller (VLC) and a current-loop controller (CLC) to control the BBC's output voltage and current to drive high-power laser diodes (HPLDs). In the start-up phase, when the BBC output side is operated from the constant-voltage mode and changed to the constant-current mode, a current overshoot occurs, which can damage the high-power laser diodes. This paper proposed a control method, the proportional-switching-proportional-integral control technology, can be used to the CLC to reduce the start-up current overshoot.

IEEE 802.11 distributed coordination function achieves only limited performance because of the considerable idle time caused by the backoff procedure and the high rate of transmission collisions at high loads. In this paper, we propose a novel reservation-based distributed medium access control (MAC) scheme for infrastructure wireless networks. The proposed reservation-based MAC scheme, with the help of an Access Point, introduces low control overheads and provides collision-free data transmission, thus maximizing system performance.

Considering the shortcomings of malfunction and too long action time of arc protection for traditional 10kV switch cabinet, arc protection system policy is designed in this article based on DSP. This system uses arc voice recognition, arc detection and current detection to identify switchgear arc fault, and has the advantage of strong data processing capability and fast operation. Meanwhile, wavelet analysis theory is applied to fault signal processing and recognition. This can provide reliable, secure fast arc fault protection for switch cabinet. Finally, partial discharge test platform is built to experiment, and the effectiveness and correctness of this strategy is verified by the experiment.

Conventional PID (Proportional Integral Derivative) control algorithm has been commonly employed in the speed controller design because of easy control and implementation. However, it cannot solve the problems due to the motor parameters and any load disturbance, not even the sensitivity. In order to obtain the dynamic speed response due to these problems, a PID control method based on a radial basis function neural network (RBFNN) is proposed in this paper. The gain parameters of PID controller are tuned by performing the RBFNN according to the variations of system parameters. Finally, a prototype of the RBFNN based motor drive for a brushless DC (BLDC) motor is designed and implemented in this paper. A comparison between conventional PID and RBFNN-based PID control is performed. The experimental results to the range hood show that RBFNN based PID control has better performance than PID control.

Based on the research of handling stability of vehicles, the semi-trailer train model is constructed by using the multi-body dynamical software Trucksim. According to the national standard ISO-3888-2-2011, the double lane change has been selected to be tested. Through the method of controlling variables, the impact of a single parametric variation on the handling stability of targeted vehicle, the impact of vehicle speed, the mass of semi-trailer train, wheelbase as well as other parameters on rollover stability will be determined. The result will provide references for designing and driving semi-trailer.

The development of big data and the Internet of Things (IoT) is rapidly accelerating and affecting all areas of communication technologies and businesses by increasing the benefits for organizations and individuals. The growth of data produced via IoT has played a major role on the big data landscape. The paper is concerned with respect to the Big Data key-value pairs from different database types using the latest version of Elasticsearch 6.0 and classic relational database as MySQL 5.5. This stands for the crucial topics since many databases are used these days and it is difficult to choose the right database for specific scenario. The correct choice for specific scenario is very important in e-applications or communication systems, because it is supposed to save a lot of money and effort. This work aims at comparing and testing Elasticsearch and MySQL DB (Database) with related frameworks e.g., Spring Data. This particular comparison is done via searching values in larger key-value datasets. At this point, it is very important to know which database to choose in this scenario, because it is often used in e-applications e.g., when e-application wants to store session ID and user time spent in e-app. Simulation scenarios in this paper were created using real data sets provided by IBM internal e-learning app. Based on performed tests, authors provide the community with a suitable way of storing data.

In order to describe the micro-grid and its dynamic performance more accurately, the state space models for the micro-grid components and systems have been developed in this paper. Considering about the interaction between inverters and effectiveness of dynamic networks, the state-space model of micro-grid including parallel voltage-controlled inverters has been proposed. Droop control has been adopted in micro-grid to automatically share power and regulate output voltage of parallel voltage-controlled inverters (VCIs) in micro-grids. The dynamic characteristics of the sources, distribution lines and control have been integrated in the developed state space model. The model focus on the detail of the control loops of the inverter but not the switching actions. The state-space model of micro-grid has been verified using Matlab/Simulink simulations.
