A single-phase bridge rectifier that supplies a very high inductive load such as a de motor is shown in Figure 3.9a. The turns ratio of the transformer is unity. The load is such that the motor draws a ripple-free armature current of I, as shown in Figure 3.9b. Determine (a) the HF of input current and (b) the input PF of the rectifier.
