Lab no Three-phase midpoint rectifiers with current filters Authors: M. Albu, R. Bojoi, M.P. Diaconescu 3 Natural commutation implies the natural transfer of the current from one branch circuit to another branch under the “pressure” of a commutation voltage that appears after the semiconductor device found on the next branch is turned on. Single Phase Diagram of Vienna Rectifier Figure 3 shows a simplified, single-phase diagram of the Vienna rectifier. To control this rectifier, the duty cycle is controlled such that it regulates the voltage vxiNdirectly. That is, if the software variable Duty is set to 1, it makes vxiN the largest voltage possible by never turning on Q1 and Q2 switches and letting the inductor connect to the. Three-phase controlled rectifiers have a wide range of applications, from small rectifiers to large High Voltage Direct Current (HVDC) transmission systems. They are used for electro-chemical process, many kinds of motor drives, traction equipment, controlled power supplies, and many other applications.
