A novel multi gradient inverter based on variable slope voltage summation with low harmonic distortion

The paper presents a multi gradient inverter with low total harmonic distortion in the output voltage. The inverter implements summation of variable voltage slope to obtain the sinusoidal output. The inverter output voltage is self-stabilized through a closed feedback loop. The inverter incorporates operational amplifier as integrator to generate variable voltage slope. Summation of these voltages produces sine wave output. The entire system is designed to give the output with low harmonic distortion without using filter circuit. To verify the presented model simulations with MATLAB/Simulink software has been conducted. Simulation results prove the validity of the model.
