LLC Converter Design Using RidleyWorks
The design of the LLC converter is simple and straightforward when using RidleyWorks. No equations are needed, and the design process becomes a pleasure for the engineer rather than a chore.
Dual Active Bridge Design Using Scaling Laws
This unique presentation is by our guest speaker Nicola Rosano. The complex process of dual active bridge converter design is greatly simplified with the application of standardized curves combined with power and frequency scaling concepts.
Magnetics and Dowell's Equations Chapters 1-4
This early report shows impressively detailed and complex application of Dowell's equations. Chapters 1-4 of the work.
Magnetics and Dowell's Equations Chapters 5-9
Only 1% of engineers will ever attempt to use this work - will you be one of them? For the other 99%, RidleyWorks does all the hard work for you.
[A07] IGBTs Challenge MOSFETs
Small die size makes IGBTs competitive in high frequency conversion.
[115] Swept Transient Frequency Response for the LLC Converter
Part III: Swept loops in LTspice® can be used for the LLC converter where no small-signal model exists.
[114] Transient Loop Sweeps Outperform Small-Signal Models
Part II: Swept loops in LTspice® provide more accurate and useful results than small-signal models.
Frequency Response Measurement Masterclass
In this two-hour webinar, we demonstrate hands-on why the measurement of Bode plots is one of the most important lab skills you can learn.

Magnetics Core Loss Webinar
In this groundbreaking webinar, Dr. Ridley demonstrates circuit models for core loss that provide loss estimations regardless of waveform. The models provide better worst-case analysis than the original data.
Happy Hour with Dr. Ridley - Webinar
This is an open discussion without any formal presentation from Dr. Ridley. Ask any questions you like about power electronics, history, frequency response, topologies, technology, people, or the past and future of our field.
Design, Build and Test a Flyback Transformer - Webinar
In this webinar Dr. Ridley shows you how to Design, Build, and Test a Flyback Transformer. We had the ambitious plan to actually build the transformer live during the webinar.
Magnetics Proximity Loss - Webinar
Dr. Ridley tackles the advanced topic of magnetics winding losses. He shows how to reduce complex analytical expressions to straightforward circuit models.
