This paper presents the realization and performance of a fully digital permanent magnet synchronous motor drive. A new control algorithm gives maximum torque to current ratio in both the constant torque region and in flux weakening. Inner loop curren

There are several ways to model three-phase gridconnected voltage-source inverters (VSIs) with an $LCL$ filter. Such models often use simplifications like constant dc-link voltage or averaging over a switching period. These simplifications remove tra

In this paper, a cascaded model predictive control algorithm is applied to a grid connected voltage source inverter with LCL filter. The cascaded approach allows the use of one switched and one linear model, hence simplifying the implementation of th

How to start a voltage source inverter (VSI) is an often overlooked topic. Many papers focus on control algorithms, assuming the inverter is already in operation. Besides inrush current, pre-charging of the DC-link capacitor is one of the most import

The use of voltage source inverters in the power grid has many advantages, but cost is always an issue. To reduce the cost, a simple but fast sensorless control method is proposed to eliminate the need for external sensors such as grid voltage measur

This paper shows an application of a Back to Back (BtB) converter interfacing a microgrid. The idea is to take advantage of the DC link part of the BtB converter to tap power to feed a remote area through DC cables. General aspects of DC transmission

This paper introduces the application of a Back-To-Back (BtB) Voltage Source Converter (VSC) to operate optimally a radial microgrid. Some pending technical issues in microgrids and how they could be solved or improved by using this proposal, as well
