FET Regulator
FET regulators are elegant devices which keep output voltage steady while input voltage drops -- yet they are as much an art as a science to develop. Everyday Practical Electronics (EPE), a British magazine, is soon to publish a design of mine -- a battery-less Wind-Up Torch / Flashlight -- at the core of which lies a FET regulator. This regulator took me weeks to develop. OBSERVATION: In fact, I first developed this torch / flashlight for the Americans, years ago -- but there is a difference in what the Americans and the British appreciate. The publisher shouldn't mind that I show the block diagram above -- it doesn't "let the cat out of the bag" as to detail, and might awaken interest in the article.
