Fonctionnement du Spécialisation
Suivez les cours
Une Spécialisation Coursera est une série de cours axés sur la maîtrise d'une compétence. Pour commencer, inscrivez-vous directement à la Spécialisation ou passez en revue ses cours et choisissez celui par lequel vous souhaitez commencer. Lorsque vous vous abonnez à un cours faisant partie d'une Spécialisation, vous êtes automatiquement abonné(e) à la Spécialisation complète. Il est possible de terminer seulement un cours : vous pouvez suspendre votre formation ou résilier votre abonnement à tout moment. Rendez-vous sur votre tableau de bord d'étudiant pour suivre vos inscriptions aux cours et vos progrès.
Projet pratique
Chaque Spécialisation inclut un projet pratique. Vous devez réussir le(s) projet(s) pour terminer la Spécialisation et obtenir votre Certificat. Si la Spécialisation inclut un cours dédié au projet pratique, vous devrez terminer tous les autres cours avant de pouvoir le commencer.
Obtenir un Certificat
Lorsque vous aurez terminé tous les cours et le projet pratique, vous obtiendrez un Certificat que vous pourrez partager avec des employeurs éventuels et votre réseau professionnel.
Cette Spécialisation compte 6 cours
Cours1
Introduction à l'électronique de puissance
4.8
1,317 notes
This course introduces the basic concepts of switched-mode converter circuits for controlling and converting electrical power with high efficiency. Principles of converter circuit analysis are introduced, and are developed for finding the steady state voltages, current, and efficiency of power converters. Assignments include simulation of a dc-dc converter, analysis of an inverting dc-dc converter, and modeling and efficiency analysis of an electric vehicle system and of a USB power regulator.
After completing this course, you will:
● Understand what a switched-mode converter is and its basic operating principles
● Be able to solve for the steady-state voltages and currents of step-down, step-up, inverting, and other power converters
● Know how to derive an averaged equivalent circuit model and solve for the converter efficiency
A basic understanding of electrical circuit analysis is an assumed prerequisite for this course.
Cours2
Converter Circuits
4.8
536 notes
This course introduces more advanced concepts of switched-mode converter circuits. Realization of the power semiconductors in inverters or in converters having bidirectional power flow is explained. Power diodes, power MOSFETs, and IGBTs are explained, along with the origins of their switching times. Equivalent circuit models are refined to include the effects of switching loss. The discontinuous conduction mode is described and analyzed. A number of well-known converter circuit topologies are explored, including those with transformer isolation.
The homework assignments include a boost converter and an H-bridge inverter used in a grid-interfaced solar inverter system, as well as transformer-isolated forward and flyback converters.
After completing this course, you will:
● Understand how to implement the power semiconductor devices in a switching converter
● Understand the origins of the discontinuous conduction mode and be able to solve converters operating in DCM
● Understand the basic dc-dc converter and dc-ac inverter circuits
● Understand how to implement transformer isolation in a dc-dc converter, including the popular forward and flyback converter topologies.
Completion of the first course Introduction to Power Electronics is the assumed prerequisite for this course.
Cours3
Converter Control
4.8
338 notes
This course teaches how to design a feedback system to control a switching converter. The equivalent circuit models derived in the previous courses are extended to model small-signal ac variations. These models are then solved, to find the important transfer functions of the converter and its regulator system. Finally, the feedback loop is modeled, analyzed, and designed to meet requirements such as output regulation, bandwidth and transient response, and rejection of disturbances.
Upon completion of this course, you will be able to design and analyze the feedback systems of switching regulators.
This course assumes prior completion of courses Introduction to Power Electronics and Converter Circuits.
Cours4
Techniques avancées de commande de convertisseurs
4.8
245 notes
This course covers advanced converter control techniques, including averaged-switch modeling and Spice simulations, modeling and design of peak current mode and average current mode controlled converters, as well as an introduction to control of single-phase ac grid tied rectifiers and inverters. Design and simulation examples include wide bandwidth point-of-load voltage regulators, low-harmonic power-factor-correction rectifiers, and grid-tied inverters for solar photovoltaic power systems. Upon completion of the course, you will be able to model, design control loops, and simulate state-of-the-art pulse-width modulated (PWM) dc-dc converters, dc-ac inverters, ac-dc rectifiers, and other power electronics systems.
This course assumes prior completion of Introduction to Power Electronics, Converter Circuits, and Converter Control
