In this paper comparative study of proposed hybrid multilevel inverter (HMI) operating in modified pulse width modulation (PWM) mode with cascaded H-bridge multilevel inverter (CHMI) is done. Two types of HMIs are proposed with same configuration. To control the two HMIs, modified PWM techniques are derived from sinusoidal pulse width modulation (SPWM) to reduce the switching losses in the inve...

This paper presents a micro controller based control of multilevel inverter for single phase Induction motor. IGBT is used as power element.

The multilevel inverter power structure plays a vital role in the power industry. It is easier to produce a high-power, high-voltage inverter with the multilevel structure. The topologies of multilevel inverter have several advantages such as lower total harmonic distortion (THD), lower electromagnetic interference (EMI) generation, reduction of voltage ratings of the power semiconductor switch...

AbstractThe low common mode voltage vector modulation technique for the three-level cascaded voltage source inverter is presented in the paper. The large number of available states for multilevel inverters can make implementation vector control strategies complicated. The main characteristic of the proposed modulation technique is its simplicity of implementation due to the fact that any availa...

Abstract: Three-phase two-level voltage source converters are used for distribution static compensator (DSTATCOM) applications and can be replaced by a multilevel inverter. In this paper, an LCL filter interfaced cascaded H-bridge multilevel inverter-based (CHBMLI) DSTATCOM is simulated and its performance is analyzed considering the system parameters. The analysis considers factors including t...
