A Hybrid PWM Technique to Improve the Performance of Voltage Source Inverters

Due to the rapid advancement of power semiconductor devices, use voltage source inverters (VSIs) has gained widespread acceptance. As a consequence, performance inverter emerged as critical aspect that is highly reliant on modulation strategy. The pulse width (PWM) technique most widely utilized method controlling switches VSI. Power quality always considered an industrial concern for VSI-based system such grid-connected renewable energy systems and motor drives which largely depends PWM used switching. However, existing schemes VSIs suffer from high total harmonic distortion (THD) loss problems. To mitigate THD VSI, hybrid been proposed in this paper. introduces modified modulating signal along with newly shaped carrier signal. A two-level VSI evaluate both without filter conditions against RL load. offers 0.89% filtered 0.69% current are lower than techniques. On contrary, at condition, shows THDs 45.77% 12.50% output current, respectively also those Apart these, reduces switching conduction losses compared simulation works carried out MATLAB/Simulink environment reduced scale experiment conducted laboratory technique.
