Abstract: Datacenter applications need low-latency data service. Proper data placement in modern distributed storage systems reduces data movement delay, which can greatly reduce service latency. Existing data placement solutions often assumed data request distribution or…
Abstract: Cloud computing environments are increasingly using container-based virtualization. Cloud vendors and users struggle to detect and analyze container anomalies. This paper proposes an online container anomaly detection system using the optimized isolation forest algorithm…
Abstract: This project presents a novel reduced sensor strategy for two-stage single-phase grid-connected solar photovoltaic systems with batteries that eliminates the dc-link voltage sensor. For voltage source converter (VSC) control and maximum power point tracking…
Abstract: Solar photovoltaic can meet rising energy demand in sunny countries. Intermittent renewable energy sources require fast system dynamics. This paper describes a grid-coupled solar photovoltaic (SPV) system with an incremental conductance-based MPPT and boost…
Abstract: A cascaded H-bridge (CHB) converter-based medium or high-voltage motor drive system with three single-phase CHB chains may experience severe second-harmonic ripple power. This issue can be solved by oversizing dc capacitors or using active…
Abstract: This letter uses fuzzy logic to switch unusually. Eliminating logic-gate design simplifies the proposed method. Fuzzy logic pulse generators are also lookup tables. Controlled membership functions (MFs) and fuzzy logic controller rules allow direct…
Abstract: This project introduces critical-conduction-mode-based modulation for three-phase bidirectional ac-dc converters. This modulation reduces switching frequency variation, achieves zero-voltage-switch soft switching, and reduces switching-related loss, which is especially beneficial for systems operating above hundreds of…
Abstract: Since a DC micro-grid has power converters connected by different line impedances, tuning the voltage controller provides a simple and intuitive tradeoff between voltage regulation and current sharing. A flexible distributed control strategy using…
Abstract: In dc microgrid systems, bus impedance, filters, and converters can cause input voltage and current oscillations in power converters with input filters. This paper introduces an oscillation-resistant solid-state single-port series damper (S 3 damper)….
Abstract: This project introduces a new output voltage regulation method for impedance control network (ICN) resonant dc-dc converters that alternates between full-bridge and half-bridge rectifiers. Topology morphing control allows the ICN converter to maintain soft…
Abstract: Energy buffers absorb twice-line-frequency power ripple in single-phase inverters and rectifiers. Large electrolytic capacitors have traditionally solved this problem. Designers use ceramic and film capacitors with active filtering converters to reduce capacitance due to…
Abstract: Brushless direct current motors with Hall sensors are used in many industrial and commercial applications due to their simplicity and low cost. Meanwhile, Hall sensor drive fault tolerant control (FTC) research has increased. Motor…
