Nov 30, 2020 · ABSTRACT: This paper presents the simulation of three phase voltage switching inverter in MATLAB/Simulink using Sinusoidal Pulse Width Modulation (SPWM) scheme. The
A three-phase Voltage Source Inverter (VSI) with SPWM (Sinusoidal Pulse Width Modulation) is a type of inverter that converts DC voltage into three-phase AC voltage with sinusoidal waveforms. It works by varying the pulse width of a high-frequency carrier signal according to the instantaneous amplitude of a reference sinusoidal waveform.
Inverter is the most important device to utilize the renewable energy sources efficiently. The Sinusoidal Pulse Width Modulation (SPWM) technique is one of the most popular PWM techniques for harmonic reduction of inverters since there are used three sine waves displaced in 1200 phase difference as reference signals for three phase inverter.
A three-phase VSI consists of six power semiconductor switches, typically insulated-gate bipolar transistors (IGBTs) or power MOSFETs, arranged in an H-bridge configuration. The switches are grouped into three pairs, each controlling one phase of the output voltage (Va, Vb, and Vc).
To generate the desired three-phase sinusoidal output, three reference sinusoidal waveforms (Vra, Vrb, and Vrc) are generated. These reference waveforms have a fixed frequency (ω) and amplitude (V m) and are phase-shifted by 120 degrees relative to each other.
