In this week’s Wine Down Friday, we sit down with Ray Ridley, CEO of Ridley Engineering, a pioneer whose career in power electronics spans decades of consulting, training, and tool development. From his early days experimenting with switching power supplies in the 1980s to building a globally respected company, Ray shares how hands-on work and practical design remain at the core of engineering excellence. He reflects on memorable consulting experiences, the philosophy behind his workshops, and why building real hardware is essential for learning. Beyond engineering, Ray talks about his hobbies—from running and sailing to tennis and music—and closes with inspiring advice for young engineers entering the power electronics field: stay curious, build often, and pursue problems with passion.
