Power Electronics — question 6 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.

The board works fine once actually running; the failure happens only at the instant of power-up.

You connect a board with about 2mF of total bulk capacitance to a bench supply. The moment you flip the supply on, its overcurrent protection trips, even though the board's steady-state current draw is well within the supply's rated current. Walk through what's happening and how you'd fix it, considering changes on both the supply side and the board side.

How sure are you?

Being confidently wrong costs more mastery than admitting a guess — that is deliberate, and it is how misconceptions get found.

Neither is graded, and nothing here is recorded.
