This circuit was found in an American documentation from 1970. We can increase the number of multiplier steps to have higher output voltage. The operating frequency is around 1.35 kHz.
The purpose of this circuit is to provide a constant current to an experimental electromagnet. The...
Suggested by Sprague in the 90's documentation, this circuit applies to AC motors. The...
This indicator with the integrated circuits CA3162E and 3161E was published in the July 1990 issue...
