Which of the following statements best describes the operation of a bridge rectifier?
1
In a bridge rectifier, current flows through two diodes during both positive and negative half cycles, leading to very high-power loss.
2
The peak inverse voltage (PIV) of diode in a bridge rectifier is the same as in a center-tapped rectifier.
3
The output voltage of a bridge rectifier consists of only DC components with no AC ripples.
4
The bridge rectifier is a full-wave rectifier that does not require a center tapped transformer, improving transformer efficiency.
