Power Electronics — question 3 of 10
Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.
Assume ideal duty cycle D = Vout/Vin for this estimate.
A synchronous buck converts 12V to 5V, switching at 500kHz with a 10uH inductor. Ignoring losses, what is the peak-to-peak inductor ripple current? Then tell me: if the load drops to 50mA, does the converter stay in continuous conduction mode (CCM), and what changes if it doesn't?
This one resolves to a number. Give the value in the field below and your reasoning in the box — the number is checked exactly, by arithmetic.
