Which of the following methods requires use of peripheral components? Correct Answer External control of DC input voltage

Peripheral components:

  • The components which are required for control of voltage other than inverters are called peripheral components and these are very much required for quality and control output.
  • In external control of dc input voltage, you can take a controlled dc output from rectifiers and chopper.
  • The output can pass through the filter for quality output or removing unwanted harmonics.
  • So these are the essential peripheral components of the External DC voltage control. 
  • ​A chopper is used to control the DC input voltage to the inverter, which then converters the variable DC to variable AC.
  • A fully controlled rectifier can be used to take controlled and variable dc output which then can be used as DC input voltage to the inverter, which then converters the variable DC to variable AC.


External control of DC input voltage:

So, from the above figure, it can be seen external control of dc input voltage requires some peripheral devices like Filters, Chopper, Ac voltage controllers and rectifiers.

A small and medium enterprise imports two components A and B from Taiwan and China respectively and assembles them with other components to form a toy. Components A contributes to 10% of production cost while components B contributes to 20% of production cost. Usually the company sells this toy at 20% above the production cost. Due to increase in the raw material and labour cost in both the countries ,component A became 20% costlier and components B became 40% costlier. Owing to these reasons the company increased its selling price by 15%. Considering that cost of other components does not change. What will be the profit percentage if the toy is sold at the new price?

Which of the following statements regarding interface circuit are correct? 1. Electrical buffering is needed when the peripheral operates at a different voltage or current to that on the microprocessor bus system or there are different ground references. 2. Timing control is needed when the data transfer rates of the peripheral and the microprocessor are different. 3. Changing the number of lines is needed when the codes used by the peripherals differ from those used by the microprocessor.
The peripheral speed is the armature peripheral speed in the stationary field coils.
The process of transferring data intended for a peripheral device into a disk (or intermediate store) so that it can be transferred to peripheral at a more convenient time or in bulk, is known as
