Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What is the duty ratio formula for a buck converter?

  • Vo = D × Vin
  • D = Vo/Vin
  • Vin = D × Vo

💡 Hint: Think about how output voltage relates to input voltage.

Question 2

A buck converter has an output of 20 V when the input is 60 V. Is the duty ratio greater than, less than, or equal to 0.5?

  • True
  • False

💡 Hint: Calculate to verify.

Challenge Problems

Push your limits with challenges.

Question 1

A designer needs to create a buck converter to supply 15 V from a 50 V input. What would the required duty ratio be, and how much time will the switch need to be ON for a 100 kHz operation?

💡 Hint: Use the duty ratio formula and reference frequency formulas.

Question 2

Consider a boost converter with an input voltage of 5 V which must output 18 V. Calculate the required duty ratio. If the load draws 20 W, what is the average current drawn from the input?

💡 Hint: Start by determining the duty ratio from the boost converter equation.
