Very informative introduction to the function and desirability of snubber circuits. Seven videos giving an overview of several chapters in a book he was writing.
Snubber circuits are designed to protect your switching device from the backlash of an inductor and also maintain your signal clarity.
I enjoyed the section on regenerative snubbers.
