Modification of SPWM Modulating Signals for Energy Balancing Purposes

There is currently a growing interest in efficient power generation and transformation without increasing the cost complexity of system. One type conversion energy from direct current to an alternating current, which used various applications, for example, photovoltaic systems. elementary components these systems inverter. However, there are several drawbacks design systems, such as balance between their semiconductor devices. Therefore, it important study alternatives thus achieve positive impact on both economic reliability aspects This article deals with study, design, implementation modification modulation technique reconstructed modulating signals, aims ensure each cell multilevel inverter and, at same time, present better results concerning different parameters comparison established, harmonic distortion, percentage unbalance, use digital resources, transferred load.
