The thyristor d.c. drive remains an important speed-controlled industrial drive, especially where the higher maintenance cost associated with the d.c. motor brushes (c.f. induction motor) is tolerable ...
The major drawbacks of conventional diode or thyristor rectifiers are overcome by active power factor correction; this further provides additional benefits. Operating principles and features of single ...
Medium power, single-phase silicon controlled rectifiers, with 25 A current handling, provide enhanced glass passivation with low thermal resistance and high dl/dt and dV/dt capabilities. America ...
En route to getting the off-the-peg DC-51 motor speed controller to better suit my small milling machine, I had a go at working out what the circuit is. Approx circuit of DC-51 motor speed controller ...
