Objectives

The main objective of the training is to provide the audience with the main modeling and control concepts needed to successfully control a single-phase or three-phase inverter for different applications: AC voltage generation (UPS, AC buses, etc.), grid-tied inverters and motor drives.

What should you expect from the training?

This course is an introductory to mid-level course focused in the following specific objectives:

• To provide a practical comparison of the main Modulation Techniques. 
• To get a solid fundamentals about the design of the digital inner current loops.
• To show efficiently how to move from the single-phase to the three-phase converters.
• To show the different grid-synchronization techniques under balanced and unbalanced conditions.
• To provide a complete set of practical reference designs (PSIM simulation examples) for the main inverters applications (voltage forming, grid-tied and motor drive) for the main filter configurations: L, LC and LCL.
• To show the most effective, current and future, digital platforms to implement the inverter control.

Audience description

The training course is recommended to everybody interested in the theoretical and practical design aspects of digital control applied to the main inverter applications:

• The practicing engineer (firmware and power hardware engineers) will be given with the physical meaning and efficient explanations of the modeling and control problem.
• The university student (Master and PhD degrees) will find easy-to-follow mathematical developments not always covered in the text books.
• Instructors and university professors will find a different approach for their explanations as well as an interesting set of simulation reference designs.
• The control expert is also invited to participate in a discussion-space to share practical experiences on specific problems.

Methodology

The focus is placed on Concepts

The explanations are focused on the concepts and physical meaning. Mathematical developments are also included as reference materials in annexes.

Tools

Controller design using SmartCtrl + PSIM simulation to test the results.

Examples & Exercises

A large number of examples are used to show training explanations. Exercises are proposed to be developed by the audience during the training.
