Trying to keep on top of the green power revolution? Seek no further. We’ve surfed the web on a quest to bring you some of the most informative and helpful videos, podcasts and other digital delights. In this week’s installment, we bring you tutorials from Texas Instruments and Microchip.

Texas Instruments has done a great job of overhauling its web site recently, including their new “E2E” technical community section. If you haven’t visited recently, it’s a lively mix of customers and TI-ers discussing everything from DSP code development to the fine details of battery management. The E2E community also is a good place to keep up with the numerous podcasets and videos that TI produces. Even though it’s not exactly related to green power, I really like their “Thank an Engineer” series which takes a look at life would be like if simple things like remote controls, cellular phones, and MP3 players had not been invented.

But I digress. The reason I’m posting today is because I stumbled on a couple of interesting green power videos. The first is a collaboration between TI and Cree about using LEDs in solar-powered lighting applications. Although there is definitely some element of pushing Cree products, the video provides some excellent nuts-and-bolts details of getting the most lumens and lifetime from your design.

If you design switch-mode power supplies (or even thinking of designing one), be sure to check out Scott Lester’s tutorial on measuring load regulation. Scott does a great job of walking you through this essential measurement technique.

But TI is not the only company who’s been cranking out helpful videos. , Mircochips’ AE Jorge Zambada has produced an excellent tutorial on Interleaved Power Factor Correction, based on Microchip’s low-cost dsPIC signal controller.
