Suggested by Sprague in the 1980s documentation, this circuit can control three-phase AC motors. The original documentation does not specify the maximum motor current.
We found this circuit in a technical documentation from the 70's. Any double-gate MOSFET can be...
We found this thyristor power supply in a 1987 documentation. It uses common SCRs as rectifiers and...
This simple circuit has its trigger point set in the trimpot. The transistor can be any general...
