Question 1
Consider a motor with torque-Speed characteristic Tm= (6ω + 8)N-m driving a load with torque TL = 10N-m. which of the following is true?
Question 2
A DC source of 100 V supplies a purely inductive load 0.1H. The controller is a thyristor in series with the source and load. The latching current specified is 100mA . The minimum width of the gating pulse to ensure thyristor turn ON is
Question 3
A non-sinusoidal load current expressed in Fourier series form as:
is produced when a sinusoidal voltage source of is applied to a non-linear load.
Determine the distortion factor of the load current.
is produced when a sinusoidal voltage source of is applied to a non-linear load.
Determine the distortion factor of the load current.
Question 4
A separately excited dc motor runs at 900 rpm from a 198 V dc supply. The motor is fed from a 230 V, 50 Hz single phase fully controlled bridge converter with a firing angle of α. If the motor runs at 500 rpm on no load, then value of α (in degrees) would be
Question 5
In sinusoidal PWM, determine the frequency of the carrier signal required, if the reference signal has a frequency of 50 Hz. The frequency modulation ratio,
