How can you convert AC to DC power?

• A. Transformer rectifier converts 115-volt AC to 28-volt DC.
• B. Static inverter converts DC to AC.
• C. APU converts AC to DC.
• D. External GPU powers DC directly.

Answer: (A)

Converting AC to DC requires a device that rectifies the alternating current into a unidirectional flow, often with a transformer to adjust the voltage first. A transformer rectifier does exactly that: it steps the 115-volt AC down to a lower AC level and then uses a rectifier to convert that alternating current into DC, with smoothing components to produce a steady DC output like 28-volt DC. The other options describe opposite or unrelated functions: a static inverter turns DC into AC, an APU isn’t specifically the AC-to-DC conversion device, and powering a DC device directly from an external GPU isn’t a conversion step.
