This paper addresses the voltage droop compensation associated with long pulses generated by solid-stated based high-voltage Marx topologies. In particular a novel design scheme for voltage droop compensation in solid-state based bipolar Marx generators, using low-cost circuitry design and control, is described. The compensation consists of adding one auxiliary PWM stage to the existing Marx st...

In recent times, interest in renewable energy-based Distributed Generation (DG) is increasing rapidly. These sources are connected to AC bus through inverter interface. During islanded mode, output voltage and frequency of should be properly regulated for stable operation it done by applying control action on inverter. The paper presents a strategy controlling output. It deals with active power...

Diffusion-weighted imaging (DWI) is an advanced magnetic resonance imaging technique, based on the analysis of thermallydependent movement of water molecules in the extracellular space. This method allows to examine pathological changes at the cellular level which are not visible on conventional magnetic resonance (MR). Apparent diffusion coefficient (ADC) is a mathematically calculated value i...

The recent changes in the structure of power generation towards a distributed generation have motivated the increasing interest in the control of so-called microgrids. Microgrids typically consist of an AC electrical network connecting a set of loads and droop-controlled inverters. While the decentralized and proportional primary droop-control ensures the stabilization and the synchronization o...

The efficiency droop in GaInN/GaN multiple-quantum well MQW light-emitting diodes is investigated. Measurements show that the efficiency droop, occurring under high injection conditions, is unrelated to junction temperature. Furthermore, the photoluminescence output as a function of excitation power shows no droop, indicating that the droop is not related to MQW efficiency but rather to the rec...

The Control System for the Advanced Light Source uses in-house designed IndustryPack (IP) I/O Modules in compact PCI (cPCI) chassis to control instrumentation. Each module consists of digital I/O ports and 16-bit analog I/O interfaced to instrumentation via a cPCI rear I/O card. During the past few years of installed operation, several factors have prompted investigation into the design of a ne...

Abstract A new power sharing method of a virtual sychronous generator control based inverters is introduced in this paper. Since virtual synchronous generator has virtual inertia and damping properties, it significantly enhances the grid stability. However, its output power considerably affects by the line impedance. Thus, in this paper, the relation between the droop control and the line imped...
