When full-wave rectification is applied to three-phase current, what type of ripple is produced?

In the context of full-wave rectification applied to three-phase current, the type of ripple produced is best described as voltage ripple. Full-wave rectification maximizes the use of the waveform by converting both the positive and negative phases of the input signal into a unidirectional output, thereby resulting in a smoother DC output compared to half-wave rectification.

In three-phase systems, the full-wave rectifier utilizes multiple diodes to effectively reduce the amplitude of the ripple voltage present in the output. This results in a ripple voltage that is significantly smaller and more uniform compared to single-phase systems. While the term "current ripple" could be related to variations in current, in this context, it is the voltage waveform after rectification that is being examined. Thus, identifying it specifically as voltage ripple provides the clarity needed in understanding the output characteristics of the rectification process in three-phase systems.
