In this paper. a novel HTS CIM was studied based on the minimization of the torque ripple and the perpendicular magnetic field component to the tape surface. The results shows that the performance of HTS materials is still not fully developed. but also needs further optimization. Based on the initial …

In this letter. a simple ESO based DC-link voltage control strategy was proposed for three-phase AC DC converter. With the proposed control strategy. additional sensors for improving system dynamic response under disturbance was avoided. which was suitable for “plug and play“ for expanding the UPS modules and microgrid. The proposed …

We have established a lower bound on load capacitance which can guarantee network stability without pre-determining the network topology. Our bound provides a theoretical foundation for ad hoc microgrids with modular source and load units. The development process for these microgrids is 1) Define acceptable voltage levels across all units …

After providing an overview of the IoT network. the wireless power transfer system is presented. It can be expressed as a state-space model where sensors deploy to get state information. Then. an innovative IoT communication infrastructure is proposed for monitoring and controlling the WPT system. Based on the communication network. …

In this paper. we investigate secure uplink transmission in a typical Internet of Things (IoT) deployment. where multiple sensors communicate with a controller via the assistance of an untrusted relay. By taking both the relay and direct links into account. three different scheduling schemes. e.g.. optimal scheduling (OS) scheme. threshold-based …

The SK Telecom Company of South Korea recently introduced the concept of IoST to its business model. The company deployed IoST. which constantly generates data via the LoRa wireless platform. The increase in data rates generated by IoST is escalating exponentially. After attempting to analyze and store the massive volume …

Low-noise sensor signals are important for digital control loops of precision switched-mode power amplifiers required to provide power output signals with an SNR of &gt.100 dB. In power electronics converters. isolated ADCs are often employed to acquire current voltage signals at a different potential. Digital signal isolators are commonly used …

Solutions for resource scarcity should be sought from urban waste management and sanitation. which are characterised by central plants and long networks. The socio-technical transition to more sustainable infrastructure is expected to include partial decentralisation based on local conditions. This paper focuses on drivers. barriers and enablers in implementing a …

In this paper. detailed exergy analysis of selected thermal power systems driven by parabolic trough solar collectors (PTSCs) is presented. The power is produced using either a steam Rankine cycle (SRC) or a combined cycle. in which the SRC is the topping cycle and an organic Rankine cycle (ORC) is …
