What are the different types of pulse width modulation techniques?
There are many derivatives of pulse width modulation techniques that are commonly used to control voltage source inverters. Some of widespread methods are sinusoidal pulse width modulation and space vector pulse width modulation techniques.
What is pulse width modulation (PWM) in a high-voltage inverter?
High-voltage inverters form an essential part of renewable energy systems, and these inverters rely on pulse width modulation (PWM) to control the power conversion process. PWM enables precision in wave generation and power quality and provides efficient harmonic suppression.
Does Pulse Width Modulation reduce harmonic distortion in voltage source inverters?
As a result of simulation studies, sinusoidal pulse width modulation has been found to have more total harmonic distortion in output voltages of voltage source inverters in the simulation. Space vector pulse width modulation has been shown to produce a more efficient output voltage with less total harmonic distortion.
What modulation techniques are used for generating variable frequency and amplitude output voltage?
These modulation techniques used for generating variable frequency and amplitude output voltage in voltage source inverters, have been simulated by using MATLAB/SIMULINK. In addition, the total harmonic distortions of the output voltages are compared.
