Correct Answer : Option (D) : pulse amplifier & pulse transformer
Explanation : The driver circuit consists of a pulse amplifier to increase the magnitude of the gate pulse to a sufficient value. The pulse transformer then provides pulses to individual SCRs.
Correct Answer : both inverter and rectifier
Explanation : Rectifier to converter the dc from the battery to ac. Inverter to charge the battery from mains.
Correct Answer : smaller conductor size
Explanation : The conductor size is smaller as there is no sink effect, and the whole conductor is utilized for transmitting power.
Correct Answer : Chopper
Explanation : SMPS (Switching mode power supply) are based on the chopper principle. The output dc voltage is controlled by varying the duty cycle of the chopper circuit.
