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.
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.
