Description
Effective implementation of Pulse Width Modulation (PWM) strategies is essential for simulating power electronic converters, particularly in the design of control systems and the analysis of system behavior. This course offers both theoretical insights and hands-on simulation experience in applying PWM strategies to commonly used power converter modules, including the half-bridge, full-bridge, and three-phase modules. Taking a unique approach that distinguishes it from typical power electronics courses, this course focuses on helping students gain a deep understanding of the capabilities and operation of power converter modules. Each power converter module and its corresponding PWM strategy is explored through detailed simulation studies in QSPICE, providing students with a strong foundation in both theory and practical application.
The use of QSPICE in this course equips students with a powerful tool for simulating and analyzing the complex behavior of power electronic converters. Unlike traditional analytical methods, QSPICE enables high-fidelity simulations that capture the dynamic operation of circuits under realistic conditions, including switching transients and control loop interactions. By simulating power converters and PWM strategies with QSPICE, students will acquire a valuable skill highly sought after in the power electronics industry. Additionally, the ability to visualize waveforms in QSPICE helps students gain a clear understanding of converter operation, enhancing their ability to analyze performance and troubleshoot real-world power electronics applications. This course, along with future QSPICE-based courses, will prepare students to become simulation experts in emerging areas of power electronics.
Who this course is for:
- Undergraduate and graduate students of electrical engineering
- Practising electrical engineers
- Power electronics researchers
Instructor
I did my Master's and PhD in power electronics after which I spent several years working for both big companies like ABB and GE as well as a number of start-ups. I specialized in the field of power converter control and smart grids and have published prolifically in high impact international journals and conferences besides also being the author of two books.
I started programming at the age of 14 and over the past 20 years have programmed in several languages - C, C++, Python, JavaScript. I started taking a keen interest in open source software after I became a Linux user when I was a graduate student.
My expertise in electrical engineering and programming therefore resulted in me creating open source software for electrical engineers. I use open source software for teaching electrical engineering to students and practicing engineers with the typical theme of my courses being the application of programming to solve engineering problems.
