Abstract:
Purpose. Increasing the output power and ensuring maximum sinusoidality of output current in a two-level voltage source inverter by implementing the overmodulation mode.
Methodology. Simulation in Matlab/Simulink environment of voltage source inverter in the overmodulation mode. Mathematical apparatus of Fourier analysis of the output current spectrum.
Findings. Modeling of the voltage source inverter in the overmodulation mode allowed obtaining a number of dependencies:
- the dependence of the VSI output power on the modulation coefficient k;
- the dependence of the total harmonic distortion of the output current and output voltage on the modulation coefficient;
- the dependence of the total harmonic distortion of the input current in VSI on the modulation coefficient.
Originality. It is established that the overmodulation mode in the voltage source inverter can significantly increase the output power and improve the sinusoidality of output voltage and output current. It is established that the dependence of the total harmonic distortion of the output current has an extremum that causes the point of maximum sinusoidality.
Practical value. The use of the overmodulation mode in a two-level voltage source inverter will ensure maximum sinusoidality of output current and minimize additional power losses in the load from higher harmonics. In addition, the overmodulation mode will significantly reduce the level of emission of higher harmonics of current into the supply network. Practical application of overmodulation mode is performed in frequency converters of the company “VО OVEN”.
