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.

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.

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.

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

  • 可以!点击您感兴趣的课程卡开始注册即可。注册并完成课程后,您可以获得可共享的证书,或者您也可以旁听该课程免费查看课程资料。如果您订阅的课程是某专项课程的一部分,系统会自动为您订阅完整的专项课程。访问您的学生面板,跟踪您的进度。

  • 此课程完全在线学习,无需到教室现场上课。您可以通过网络或移动设备随时随地访问课程视频、阅读材料和作业。

  • The specialization is designed to be taken over 24 weeks. Each course is 3-5 weeks in length.

  • The first course of the specialization, Introduction to Power Electronics, will begin every four weeks.

  • Knowledge of circuits and electrical engineering fundamentals at the level of an undergraduate EE major is assumed.

  • Generally yes. Each course builds upon the knowledge gained in the previous course.

  • At this time the University of Colorado Boulder is not offering university credit for this program. However, completion of this specialization would be a compelling resume item for application into any graduate program in Power Electronics, including at the University of Colorado Boulder College of Engineering & Applied Science.

  • Students completing this specialization will be able to:

    ●Analyze, model and simulate switched-mode power converters

    ● Design converters, including magnetic components, based on efficiency, power density and cost trade-off targets.

    ● Design high-performance voltage-mode and current-mode control loops

    ● Design a complete state-of-the-art power electronics system in a capstone project

  • This course will target three types of learners: Working engineers needing training in the specialization of power electronics, undergraduate and graduate students who wish to learn about power electronics, and other learners having curiosity about power electronics and its applications such as renewable energy, energy efficiency, and powering computer or mobile electronics.

  • Yes. If you completed Introduction to Power Electronics before January 2016, you’ll receive equivalent credit for the first three courses in this Specialization: Introduction to Power Electronics, Converter Circuits and Converter Control.
