Instructors: – Dr. Antonio Lázaro (Carlos III University of Madrid, Spain): Biography

The course starts at 9:00 a.m. and ends at 6:00 p.m. every day.


Public and technical background required

The training course is recommended to everybody interested in the theoretical aspects and practical design issues of digital control of voltage source converters. Having previous experience in power electronics and circuit simulation is useful, but beginners with no background in those topics will also benefit from the course.


 

Objectives

The objective of the course is to acquire the basic abilities about controller design for voltage source converters. Starting with a basic study of the control problem, the more important control structures will be covered together the main aspects to be into account in the digital implementation. Design procedures based on software tools like PSIM and SmartCtrl will be applied and illustrated through practical design cases.

Day 2:
 

Section V: Three-Phase Voltage-Source Inverter (AC Voltage Generation) 

Section VI: Complete digital design of Three-Phase Grid-Tied Voltage-Source Inverter: SmartCtrl design PSIM simulation and HW experiments


 

Methodology

The overall methodology is based on theoretical explanation on main concepts and details followed by practical implementation of the complete design procedure: controller design by means of SmartCtrl, PSIM simulations and hardware validation by means of a scale – down prototype.

A complete set of SmartCtrl and PSIM exercises already developed will be provided to the audience together with the rest of course materials.During practical exercises, attendees will be asked to change some component values and/or modify the schematics of the provided examples and carry out simulations.For hardware experiments SmartCtrl Console will be used to modify control parameters of a digitally controlled three-phase PFC. Attendees will experiment different effects of the digital control design by means of reference and output current step changes.
