Single-phase full-wave controlled rectifier circuit

Figure 2-9: Single-phase full-wave controlled rectifier circuit and waveforms. A single-phase full-wave and single-phase full-control bridge are essentially the same when considering the DC output or the AC input.

The differences between the two:

(1) The structure of the transformer in a single-phase full-wave system is more complex, requiring more copper and iron for its windings and core compared to a single-phase full-control bridge. This makes it slightly more expensive and resource-intensive to manufacture.

(2) A single-phase full-wave system uses only two thyristors, which is fewer than the four required for two single-phase full-control bridges. This means there are two fewer gate drive circuits, but each thyristor in the single-phase full-wave system will be exposed to twice the maximum voltage compared to those in a single-phase full-control bridge.

(3) The single-phase full-wave circuit contains only one thyristor, which reduces the number of components and the associated tube voltage drop. Taking points (2) and (3) into account, the single-phase full-wave circuit proves advantageous in applications where lower output voltages are needed.
