Objectives:

The AC-DC front-end converter is a critical element in electric-vehicle battery chargers, high power rectifiers for Hydrogen production, generator-side converter in wind turbines, general motor drives, power supplies, aerospace active rectifiers, variable speed diesel generators, etc.

The main objective of this course is to study theoretical aspects and practical aspects of the design of power factor correction (PFC) converters. This type of AC/DC rectifiers have to comply with strict specifications regarding the current harmonics injected to the grid, and more recently with some other Grid-Codes requirements.

The course is designed to provide fundamental knowledge about the design of the power stage (semiconductors, inductors, EMI filters and capacitors selection) and the control system (analog and digital). Regarding the control system, it will be covered from basic analog IC controllers (CCM and BCM) to sophisticated System on Chip (SoC-FPGA) implementation.

This training covers the basis of each topic but it can be considered as mid-level to high-level course focused in the following specific objectives:

Power stage design

To provide a practical comparison of the main PFC topologies, for single-phase and three-phase AC-DC converters.
To get solid fundamentals about the power losses calculation in the switches, as indispensable tool to design the converter. Different switches alternatives will be also shown.
To show an efficient method to design inductors for PFC converters.
To show how to obtain a correct selection of capacitors for PFC converters.
To provide an efficient methodology to design EMI filters for PFC converters.
To provide PSIM reference designs from the basic boost PFC to the sophisticated interleaved multi-phase totem-pole PFC with Triangular Current Mode operation and ZVS switching.

Control design

To show efficiently how design the analog control for single-phase applications in both conduction modes CCM and BCM. In each case it will be considered the most common used IC controller.
To show how to move from analog control to digital control.
To show the different grid-synchronization techniques under balanced and unbalanced conditions.
To provide practical knowledge about the control of the main three-phase converters: boost rectifier, buck rectifier and Vienna rectifier. L and LCL filters are covered.
To explain as simply as possible, but not simplistically, the dynamic interaction between the three-phase EMI filter and the three-phase PFC
To provide a complete set of practical reference designs (PSIM simulation examples, SmartCtrl design examples) for the main PFC applications.
To show the most effective, current and future, digital platforms to implement the PFC control.

Audience description:

The training course is recommended to everybody interested in the theoretical and practical design aspects of the power stage and analog / digital control applied to the main PFC applications:

The practicing engineer (firmware and power hardware engineers) will be given with the physical meaning and efficient explanations about the power stage design, 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 power hardware and control expert are 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.
