The AC-DC front-end converter is a critical element in electric-vehicle battery chargers, 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

Control design


Audience description:


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

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

A large number of examples are used to show training explanations.

Exercises are proposed to be developed by the audience during the training.

SmartCtrl files and PSIM files are provided in advance to develop efficiently the examples and exercises.
