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. The specific l...

In this project, a multilevel inverter was designed and implemented to operate a stand-alone solar photovoltaic system. The proposed system uses selective harmonics elimination pulse-width modulation (PWM) in the multilevel inverter to convert DC voltage from battery storage to supply AC loads. In the PWM method, the effectiveness of eliminating low-order harmonics in the inverter output voltag...

The paper presents a new STATCOM system based on H-bridge inverter. It can be used in mine power network. It has been commonly verified for the positive effects of SVG on the reactive power compensation and voltage fluctuation suppression. This paper focuses on a generalized structure of multilevel power converter where individual voltage sources are not necessarily the same. The cascade H-brid...

This paper deals with the multiband hysteresis control technique which tracks the desired reference current and provide desired voltage and current waveform with less distortion for grid connected systems. Cascaded H bridge multilevel inverter is used in high power and medium power applications. Multiband tracks the desired reference current and is used for evaluating the performance of multile...

This paper presents different kinds of grid-tied cascade H-bridge inverter and has a look to predictive current control technique. Finally the simulation result will show a Model predictive current control of a five-level cascaded H-bridge (CHB) inverter indifferent sampling times by using MATLAB Simulink software.

This paper presents detailed modeling and simulation of a compensator for Load balancing and harmonics Compensation based on a five-level cascaded H-bridge multilevel voltage source inverter. This type of compensator, which is installed in parallel with the load, is usually referred to as the shunt active power filters (APF). Nowadays use of high voltage non-linear loads are widely used in indu...

The concept of multilevel inverters introduced about 20 years ago entails performing power conversion in multiple voltage steps to obtain improved power quality, lower switching losses, better electromagnetic compatibility, and higher voltage capability. The benefits are especially clear for medium-voltage drives in industrial applications and are being considered for future naval ship propulsi...
