The research article “An Energy-Efficient Control Method of a Photovoltaic System Using a New Three-Phase Inverter with Reduced Common Mode Voltage” introduces a space vector pulse width modulation (SVPWM) technique for a new three-phase inverter (NTPI) aimed at photovoltaic (PV) applications. This method, as per the company, reduces switching losses, peak values, and dv/dt of the common mode voltage (CMV) with fewer switches, enhancing efficiency and reducing leakage current. This advancement also optimizes electric vehicle applications by lowering bearing failures. The new SVPWM’s performance was evaluated against existing PWM methods and active zero state PWM (AZSPWM) of the two-level inverter under identical conditions through experiments and MATLAB simulations.
