Hybrid trapezoidal modulation technique for conditioning of power quality and harmonic distortion based on D-statcom

In many research paper difference type of modulation technique have been used but this paper carried out by developing four modulation strategies to give a comparative analysis of trapezoidal PWM, unipolar trapezoidal PWM, bipolar trapezoidal PWM and hybrid trapezoidal PWM by using d-q control system. In this all techniques trapezoidal use as reference signal for generating the switching pulse applied on two level inverter which is based on DSTATCOM. Improvement and performance of power system is analyzed by FFT of THD for voltage and current. Simulation and experimentation have been done on MATLAB/SIMULINK.
