What components were primarily used in the earliest power supplies to convert alternating current to direct current?
Answer
Large transformers and rectifiers
Early power supplies utilized large transformers to step down the input voltage, paired with rectifier circuits, often using vacuum tubes, to convert the alternating current into pulsating direct current. These designs were characterized by their massive size, heavy weight, and significant heat production, as they were inefficient at converting energy compared to later technological advancements.
