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.


Training Objectives

The objective of the course is to acquire the fundamental competences in single-phase and three-phase PFC converters. These competences are:

  • Selection of the best topology for each type of application (EV chargers, motor drives, aerospace AC/DC front-end converters and power supplies).
  • Inductors design under the specific requirements of the PFC operation. Effective Cots inductor selection.
  • EMI filter design.
  • Power losses calculations and MOSFET / IGBT / Diodes selection.
  • Dynamic analysis of dynamic modeling of PFC converters.
  • Simple but deep understanding the PFC control loops.
  • Effective analog and digital controller design using SmartCtrl.
  • Effective PSIM simulation of 1-ph & 3-Ph PFC converters (including conducted EMI estimation by simulation).

In addition to the topology selection, specific aspects regarding the previous competences will be shown for each type of application.


Intended audience:

The training course is recommended to everybody interested in the theoretical aspects and practical design issues of PFC converters.

The course methodology and materials, together a complete set of simulations, design examples and theoretical explanations grouped in annexes make this course very useful for both, the practicing engineer and university instructor and researcher.

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.

Methodology:
The overall methodology is based on theoretical explanation on main concepts and details followed by by PSIM simulations and controller design by means of SmartCtrl.
  • 60% theoretical contents
  • 40% practical exercises by means of guided PSIM simulations and SmartCtrl designs

 

The course has been developed to serve as reference material for future designs. The main theoretical aspects are covered in the slides explanation from a conceptual point of view. Mathematical developments are provided in a set of well-organized annexes. The theoretical concepts are shown using a complete collection of ready-to–run PSIM simulations from basic simulations to complex circuits: e.g. 3-ph boost PFC + EMI Filter and LISN.

In the control sections, SmartCtrl reference designs will provide a simple way to design the controllers that can be also used for future designs.

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.
