Founder/CEO/Principal Engineer
Power Induced Design

I'm a native of Baltimore, Maryland, USA. I studied electronics engineering at Virginia Tech, where I got started in power electronics by working as an undergraduate laboratory assistant at the Center for Power Electronic Systems (CPES). I also worked on the university's hybrid electric vehicle team. From there, I started working at National Semiconductor developing DC-DC control IC's in 2001. While at NSC, I discovered the world of high power LED's, and developed several LED driver IC's. In 2008 I had an opportunity to move to Spain as a Field Applications Engineer. I held several positions at NSC in Europe until the merger with Texas Instruments. While at Texas Instruments I worked or more AC-DC power supply support and design. In 2013 I started my own electronics consulting, business, Power Induced Design. I have several regular clients, and I'm always open to new and interesting consulting or contracting possibilities.

The PFC converter is the base of the “power pyramid” of an AC-DC power supply.

Control loops and startup for PFC converters

The power factoring correcting (PFC) converter does not often get a lot of love or attention. For low and medium power levels (let’s say up to 1000W or so), a suitable reference design is often copied and then little time is budgeted for testing and proving it. Yet this part of an AC-DC power supply unit (PSU), is the base for the rest of the design.
