This paper examines the scope for network platform business models offering 'automobility-as-a-service' to disrupt existing automotive market and industry. The uses three examples (Getaround, BlaBlaCar Uber) illustrate distinct versions of model concept. Despite expectations that automobility-as-a-service, enabled by digital platforms, may erode new cars individual car ownership, argues it is not necessarily disruptive incumbent companies. Rather, via automobility-as-a-service are argued be...
The voltage produced by photovoltaic (PV) modules is much lower than grid voltage, and it difficult for the traditional boost grid-connected inverters to provide sufficient gain single PV module. Furthermore, leakage current can cause harmonic distortion potential safety risks. In order solve these problems, a common-ground inverter with high proposed in this paper. based on Cuk converter. A coupled-inductor an intermediate capacitor are connected series enhance capability. Bipolar output...
Abstract Driven by the concept of wisdom education and development needs times, personalized teaching has become a new requirement for quality talent cultivation under national innovation-driven strategy, it is inevitable trend current reform. This paper builds system in era smart education, based on characteristics local comprehensive universities. Face recognition technology used to analyze learning behavior students campus, combined with virtualization bilateral resources integrate...
This paper presents an analysis, informed by socio-technical transitions theory and the socially derived concept of automobility, impact SARS-CoV-2 virus resulting COVID-19 pandemic on automobility in Europe. The argues that a pervasive, sudden, powerful crisis has not previously be explored literature. strong behavioural changes physical virtual mobility associated with are argued to particularly significant, representing ‘living lab’ which explore possibilities for disintegrating...
Avoiding cracking defects is crucial to ensuring processability in the laser powder bed fusion (LPBF) of metallic materials. In this study, a crack-free Ni-based superalloy with high volume fraction γ′ phase was designed for LPBF process using thermodynamic approach. The results indicate that SD01 alloy and over 21% spherical uniformly distributed matrix after heat treatment. addition, 1 wt.% TiB2 particles were introduced into further enhance high-temperature mechanical performance. It...
Aiming at the key problems of existing nonisolated photovoltaic (PV) inverter, such as common mode (CM) leakage current, voltage up and down ability, service life restricted by electrolytic capacitor, a novel single-stage common-ground zeta-based inverter with nonelectrolytic capacitor is proposed in this article. The based on zeta dc converter has inherent conversion characteristics converter, which makes it more suitable for PV system wide input fluctuation range. In addition, structure...
A shunt active power filter (APF) based on cascade multilevel converters with carrier phase shifted sinusoidal pulse width modulation (CPS-SPWM) is presented. The main sections of the APF such as switching strategy, harmonic and reactive current detection, AC side control DC are discussed. Simulated results given that verify this can compensate correctly validly.
Considering the importance of line fundamental impedance from inverter to point common coupling (PCC) in microgrids, this study analyzes influence on system stability.Line values not only apply decoupled droop control, which can realize accurate control between active and reactive power, but also regulate coefficient eliminate circulation, power sharing, improve stability when a multi-distributed generation operates parallel.Moreover, PCC sense grid fault basis variations impedance.A novel...
This paper adopts a main circuit structure with back-to-back PWM converter, in which generator-side using direct torque control method, and grid-side three-phase VSR inner current decoupling based feed forward algorithms, this proposes an improved MPPT methods, can achieves more quickly effectively tracking the maximum power. Finally, effectiveness of new method is verified by simulation Matlab/Simulink environment, results confirm that DC side voltage keep constantly unity power factor...
