If you need to get up to speed with power supply design fast, then this workshop is for you.

Learn to design power supplies online from ground up with Dr Ali Shirsavar in this unique online course. Delivered as an online, self-paced course, it teaches a structured and repeatable methodology for designing real power supplies, from initial specifications through to complete component selection and documentation. Unlike many university courses, this workshop focuses on practical hardware design skills that can be applied directly to product development projects for practicing engineers new to power supply design. An in-person, hands-on version of this workshop is also available. Click here for details.

Using numerous bite-sized videos recorded by Ali himself as well as presentations, end-of-chapter quizzes, and design examples, each participant will learn how to design and select each component until the power supply design is complete. By the end of the workshop, you will have designed a complete and fully functioning power supply, with all component specified down and selected. You will have the tools and methods needed to repeat the design process for other power supply specifications.

The design methods and engineering principles learned are directly transferable to all other DC-DC power supplies, and a detailed Buck example is given. In addition, all participants will receive a free license* for our advanced Power Supply Design Software WDS capable of designing most hard-switched power supply topologies.

This workshop will take approximately 40 full-time hours to complete and counts toward your Continuing Professional Development (CPD). Upon completion, you will receive a certificate for your personal development file, recognizing your achievement in power supply design.

These workshops are designed for electronic engineers who:

• Are involved in the design, review, or specification of power supplies
• Need to rapidly get up to speed with power supply design for real projects
• Want practical experience translating datasheet parameters into real design decisions
• Want confidence in component selection with appropriate safety margins for production ready power supplies
• Need to add a minimum of 40 hours of continuous professional development hours to their portfolio
• Wish to become a specialist in power supply design

Optional Hands-On Labs (Add-On)

For participants who wish to gain hands-on practical experience, optional hands-on labs are available as a companion to the workshop. These extra labs are not required for completion of the workshop and are provided purely to enhance the learning experience. They follow a complete Asynchronous Buck converter design example from specification to component selection and include self-guided laboratory exercises using a dedicated learning board from Würth Elektronik.

To work through these optional labs, you will need access to an oscilloscope (with a bandwidth of better than 50MHz), a soldering iron, the Würth Elektronik Buck Converter Learning Kit (part number 988113), a small 12 V, 10 W power supply, and suitable resistive loads. Full instructions will be provided upon registration.

The Würth Elektronik learning board referenced in the optional labs is provided separately by Würth Elektronik and may not always be immediately available for purchase. This does not affect participation in or completion of the workshop, and the hands on exercises may be carried out when the hardware becomes available.
