The evolution of semi-conductor switches has resulted in their increased use in electrical and electronic devices in recent trends. The growing use of thyristor-based rectifiers has caused the power grid to face severe harmonic problems. In power systems, voltage unbalance occurs often. The primary source is uneven distribution of single-phase loads throughout all phases. If a three-phase fully controlled rectifier is connected with an unbalanced grid it results in voltage ripple. In this project the analysis of three phase rectifier with resistive load is done. Simulation is done in MATLAB with various voltage imbalances and the ripple factor is found. The hardware analysis is also done with voltage unbalance and the output ripple factor is analyzed. The analysis shows that the unbalance in the input voltage increases the switching losses and voltage ripple. This influences the switch conductive intervals and further distorts the input current waveform.
