A boost converter has an input voltage Vin= 10 V, switching
frequency fs= 100 kHz, duty ratio d=50%, load resistance RL= 20Ω,
inductance 100μH, and capacitance 680 μF.
If you were trying to make a boost converter enter DCM, but your
load resistor could not reach Rcrit, what other controllable
parameters (not including Vin) could you change to reduce
the lowest value of i_L to zero? Explain your reasoning.
