Circuit delivers constant power to a load

Kiril Karagiozov @ edn.com has a circuit idea that is able to deliver constant power to a load. This is done by generating energy pulses, independent of resistance of the load. If you have a load with a variable or poorly specified resistance and want to regulate the power applied to...
