Digital Controller Development Methodology Based on Real-Time Simulations with LabVIEW FPGA Hardware-Software Toolset [PDF]
In this paper, we exemplify the use of NI Lab-VIEW FPGA as a rapid prototyping environment for digital controllers. In our power electronics laboratory, it has been successfully employed in the development, debugging, and test of different power ...

Coordinated Control of Wind Energy Conversion System during Unsymmetrical Fault at Grid
High penetration of wind power into the grid necessitates the coordinated action of wind energy conversion systems and the grid. A suitable generation control is required to fulfill the grid integration requirements, especially during faults.

Power loss investigation in HVDC for cascaded H-bridge multilevel inverters (CHB-MLI) [PDF]
In the last decade, the use of voltage-source multilevel inverters in industrial and utility power applications has been increased significantly mainly due to the many advantages of multilevel inverters, compared to conventional two level inverters ...

A voltage-source inverter for microgrid applications with an inner current control loop and an outer voltage control loop [PDF]
Distributed generation (DG) units are commonly inter-faced to the grid by using voltage-source inverters (VSI’s). Extension of the control of these inverters allows to improve the power quality if the main power grid is disturbed or disconnected. In this

The paper studies the problem of invertibility of recursive operators which map \({\mathcal F}\) to \({\mathcal F}\), where \({\mathcal F}\) is a class of functions. Four increasingly stronger types of invertibility are introduced and it is shown that they are different.

Precise modelling of switching and conduction losses in cascaded h-bridge multilevel inverters [PDF]
Nowadays, voltage source multilevel inverters are being used extensively in industry due to its many advantages, compared to conventional two level inverters, such as higher output voltage at low switching frequency, low voltage stress(dv/dt), lower ...
