Simple Electronic Load Controller (ELC) Circuit for Hydro Power Systems

The post explains a simple electronic load controller or governor circuit which automatically regulates and controls the rotational speed of a hydro electric generator system by adding or deducting an array of dummy loads. The procedure ensures a stabilized voltage and frequency output for the user. The idea was requested by Mr. Aponso

Mosfet Protection Basics Explained - Is your Mosfet Smoking?

Even after connecting everything correctly you find the mosfets in your circuit becoming HOT and blowing off within minutes. This is quite a common issue faced by most new as well as experienced hobbyists while designing and optimizing mosfet based circuits especially the ones which involve high frequencies.

Connecting Voltage Regulators 78XX in Parallel for Higher Combined Current Output

Voltage regulator chips mostly have their maximum current output specs fixed to some predetermined levels. Increasing them to a higher level would normally call for external out board transistors and complicated associated circuitry which might be difficult to configure for the new hobbyists. Putting a few of them in parallel, possibly solves the problem.
