- Power quality problems in power systems have been i mproved due to nonlinear loads. To compensate these problems Direct Power Compensator was suggested in this paper. A Direct Power Compensator (DPC) is proposed in this paper to reduce the harmonic curre nts,compensate power factor and voltage unbalance problems generated by the nonlinear loads present i n three phase systems. A DPC contains back to back converter by sharing the same dc link power and v/v transformer to provide a voltage balance in transmission line. Hysteresis harmonic current regu lator is used to create pulse for back to back conv erter. A controller maintains the dc-link voltage and compen sates the power factor,harmonic currents. A comparative analysis for traction system with and w ithout DPC was performed using MATLAB Simulink. Simulation results show the controller advantages a nd the applicability of the proposed method in rail way systems. https://www.ijiert.org/paper-details?paper_id=140430
