Which type of rectifier circuit uses two diodes and a center-tapped transformer?

A standard full-wave rectifier utilizes a center-tapped transformer and two diodes. The center tap serves as the common ground return, while each diode conducts during alternating halves of the AC cycle, allowing both positive and negative halves of the AC waveform to be converted to DC. This design differs heavily from a full-wave bridge rectifier, which requires four diodes but does not need a center-tapped transformer. A half-wave rectifier, on the other hand, uses only one diode and captures just one half of the AC cycle.
