Selective Harmonic Elimination PWM (SHEPWM) is a classical method of voltage control of the inverter while eliminating the undesirable lower order harmonics for low-frequency applications. Multivariable non-linear equations often result in SHE modulation scheme. In this work, a Most Valuable Player Algorithm (MVPA) has been applied to solve the non...

Nowadays, the multilevel inverter has gained huge attention and has become more popularized in high voltage and high-power applications with low harmonics. As the number of output voltage increases, the harmonic content of the output voltage waveform decreases. In this paper, a comparison of cascaded H-bridge and cross-switched multilevel inverters...

ABSTRACT This document shows the results obtained by implementing a multicarrier SPWM level displacement control system to a single-phase seven level cascade H-bridge inverter. The tests consisted of using three multicarrier methods with different modulation rates in frequency and for every one different modulation rates in amplitude. Obtaining a s...

Power converters have been widely used in power systems to improve the quality and magnitude of the power drawn from renewable energy sources. An LCL filter for connection of an inverter to the grid is often used to reduce the harmonics generated by the inverter. Based on the different design methodologies, optimal parameters of LCL filters tend to...
