Current Source Inverter delivers predetermine AC output from a single or more DC sources due to its high impedance DC power supply. Multicarrier PWM strategy is a comparison of a reference waveform, with vertically shifted carrier signals. In multicarrier PWM technique, m ? 1 triangular Pulse-width modulation (PWM) schemes are used to synthesize the output voltage of a VSC [1]. In PWM methods switching instants are chosen so that the desired fundamental component is obtained while acceptable harmonic performance is achieved. The Voltage Source Inverter is generating AC square wave and sinusoidal current.The best performance of VSC can be achieved by different modulation techniques. The paper also discussed the different configurations of PWM techniques for harmonic reduction and The basic concepts of pulse-width modulation are illustrated in Figure 3-55. Figure 3-55a shows a single-phase PWM inverter circuit using IGBTs. FIGURE 3-54 (a) A three-phase voltage source inverter using power transistors. 190 chapter 3 introduction to power electronics. 1.
