Q For a three-phase, fully controlled, recti?er-fed, separately excited dc motor, corresponding to ideal no-load operation, find the expression for the no-load speeds. Comment on whether no-load speeds could be negative. Compared to the one- phase case, would you expect a considerable reduction in the zone of discontinuous conduction?
Q. Assuming the diode to obey I = IS (e V/0.026 -1), calculate the ratio V/I for an ideal diode with I S = 10 -13 A for the applied voltages of -2,-0.5, 0.3, 0.5, 0.7, 1.0, and
Execution Unit receives program instruction codes and data from BIU, implements these instructions and store the result in general registers.
