Multilevel inverters are becoming more popular in field of high power energy control because of their capability for high power applications. On the other hand, they require switching control methods to generate sinusoidal output with less harmonic. Cascaded H-bridge inverter has desirable features compared to diode-clamped and flying capacitor inverter; it can prevent extra clamping diodes or voltage balancing capacitors, each level has the modular structure, and there are no voltage balancing capacitors or extra clamping diodes, so packaging and modularized circuit layout is possible. In this paper, 7-Level Cascaded Multilevel Inverter is designed and four various Multicarrier PWM methods namely, Phase Disposition (PD), Phase Opposition Disposition (POD), Alternative Phase Opposition Disposition (APOD), Phase Shifted (PS) have been analyzed using MATLAB Software.
Keywords
