Webb6-Pulse Converter. The figure below shows a six-pulse bridge controlled converter connected to a three-phase source. In this converter, the number of pulses is twice that of phases, that is p = 2m. Using the same converter configuration, it is possible to combine two bridges of the six-pulse to obtain a twelve or more pulses converter.
