Distributed generation is understood as all those sources of electrical energy that are connected in the electricity distribution networks. These distribution networks have been planned with wide operating margins, which together with the characteristic t... see more

Low-voltage on the surface electrocardiogram (ECG) is classically defined as peak-to-peak QRS voltage less than 5 mm in all limb leads and less than 10 mm in all precordial leads. There are many causes of low QRS voltage (LQRSV), and they can be different... see more

The paper presents an implementation of ultra low voltage second generation current conveyor (ULV-CCII). The methodology adopted for the design is the use of level shifting stage to lower the effective threshold voltage of the PMOS differential pair trans... see more

Propose: Standard electroporation and electrochemotherapy caused the endothe- lial cell permeability and reduction in tumor blood flow. The effects of low voltage and high frequency electroporation on the endothelial cells permeability and viability were ... see more

The traditional configurations of power systems are changing due to the greater penetration of renewable energy sources (solar and wind), resulting in reliability issues. At present, the most severe power quality problems in distribution systems are curre... see more

A cost-effective light-emitting diode (LED) current balance strategy using a variable voltage regulator (VVR) with low dropout vDS control is proposed. This can regulate the multiple metal-oxide-semiconductor field-effect transistors (MOSFETs) of the line... see more

A novel control strategy is proposed in this paper for the rotor side converter (RSC) of doubly-fed induction generator (DFIG)-based wind power generation systems. It is supposed to enhance the low-voltage ride-through (LVRT) capability of DFIGs during gr... see more

This paper aims to explore a viable solution for a doubly-fed induction generator (DFIG)-based wind farm to meet the reactive support requirement of the low voltage ride-through (LVRT) grid code with safe grid-connected operation during asymmetrical grid ... see more

The Voltage Source Converter-HVDC (VSC-HVDC) system applied to wind power generation can solve large scale wind farm grid-connection and long distance transmission problems. However, the low voltage ride through (LVRT) of the VSC-HVDC connected wind farm ... see more
