STEP-UP CONVERTERS In a step-up converter, consider all components to be ideal. Let V, be 8–16 V, V, = 24 V (regulated), ƒ, = 20 kHz, and C = 470 µF. Calculate Lmin that will keep the converter operating in a continuous-conduction mode if P, 2 5 W. In a step-up converter, V, = 12 V, V, = 24 V, 1, = 0.5 A, L = 150 µH, C = 470 µ.F, and f, 20 kHz. Calculate AV, (peak- peak). In Problem 7-8, calculate the rms value of the ripple in the diode current (which also flows through the capacitor).
