What is SV PWM technique for three-phase voltage-source inverter (VSI)?

The SV PWM technique for three-phase voltage-source inverter (VSI) is addressed in this application. The structure of a typical three-phase VSI is shown in Figure 2. As shown below, Va, Vb and Vc are the output voltages of the inverter. Q1 through Q6 are the six power transistors that shape the output, which are controlled by a, a’,b, b’,c and c’.

What is three-phase pulse width modulation (PWM)?

The Three-phase Pulse Width Modulation (PWM) generates carrier-based, center-aligned PWM to trigger the switches of a three-phase inverter. The module also introduces a configurable dead time to avoid dead short circuits.

What is a three-phase inverter bridge?

System-Level Block Diagram of Three-phase PWM The three-phase inverter is the core of any AC motor drive. PWM pulses generated by the three-phase PWM drive the inverter bridge. The following figure shows the inverter bridge. Figure 1-2. Three-phase Inverter Bridge

Does SV PWM reduce harmonic distortion in a three-phase voltage-source inverter?

It has been shown that the SV PWM technique utilizes DC bus voltage more efficiently and generates less harmonic distortion in a three-phase voltage-source inverter. This document has presented an overview of SV PWM theory and two ways of SV PWM implementation.
