DC-DC Converters MCQs

Practice DC-DC Converters MCQs with four options, answers and explanations for focused Electronics & Telecommunication Engineering revision.

Question 1
Power ElectronicsDC-DC Converters

An ideal boost converter is used when the required DC output voltage is generally?

  • AGreater than the DC input voltage
  • BAlways zero
  • CLess than the input in every case
  • DAC rather than DC
Report an error
Correct Answer: A. Greater than the DC input voltage
Explanation: A boost converter raises the DC voltage magnitude under ideal continuous-conduction operation.
Reference: Standard power electronics: dc-dc converters
Question 3
Power ElectronicsDC-DC Converters

The ideal inverting buck-boost converter output voltage is given by?

  • AVo/Vs = -D/(1-D)
  • BVo/Vs = D
  • CVo/Vs = 1/(1-D)
  • DVo/Vs = 1-D
Report an error
Correct Answer: A. Vo/Vs = -D/(1-D)
Explanation: The basic inverting buck-boost converter produces an output of opposite polarity with magnitude D/(1-D) times the input.
