Multilevel voltage source inverter has been recognized as an important alternative to the normal two level voltage source inverter, especially in high power application. Using multilevel technique, the output voltage amplitude is increased, switching devices stress is reduced and the overall harmonics profile is improved. Three presentable topologies can b considered for multilevel inverter (ML...

The phase synchronous inverter is an electrical inverter device which is synchronizing inverter phase with the micro-grid phase. Generally, DC voltage supply is considered as the input of the DC to AC inverter which is a renewable energy source such as solar panel, wind turbine and battery storage, etc. The three phase three layer phase synchronous inverters are normally utilized in the high po...

A soft-switched inverter is derived from the passively clamped quasi-resonant link circuit with three different clamps: coupled inductor, diode clamp and coupled inductor and capacitor. The proposed soft-switching inverter is formed from the traditional pulse-width modulated (PWM) inverter by simply augmenting with auxiliary resonant circuits, and the soft switching is achieved through applying...

This paper presents an active solution to a commonmode voltage created by typical three-phase inverters. It is shown that the addition of a fourth leg to the bridge of a threephase inverter eliminates the common-mode voltage to ground created by the modulation of the inverter. An appropriate fourphase LC filter is inserted between the inverter and the load in order to create sinusoidal output l...

The proposed algorithm offers a novel method for minimizing ...

In high power high voltage application BLDC motor are widely used because of high efficiency, simple construction, low cost less maintenance and high torque or high output power per unit volume. For driving the BLDC motor we required inverter. PWM inverter which gives good performance. In two level inverter there is a problem of harmonics distortion, lower electromagnetic interference, high DC ...

The role of multilevel inverters in improving power quality has been already proved long back ago. The major concern in using multi level inverters is the number of switches used in it. As the level of inverter increases. So there is a need to reduce the component count in multilevel inverter. In this paper we use a statcom which is consists of a multilevel inverter with reduced switch count. T...

This paper explains a control strategy SHE-PWM and a closed loop control of the cascaded multilevel inverter based on the modulation index. The modulation index is taken as the feedback to the cascaded multilevel inverter, the proposed system reduces the total harmonic distortion by optimizing the angles of the inverter and the DC voltage sources applied to the cascaded inverter.
