Abstract:

  In this paper, a single-phase multilevel inverter with battery balancing is proposed The voltage source inverters produce a voltage with levels either 0 or ±V dc they are known as two level inverters. To obtain a quality output voltage or a current waveform with a minimum amount of ripple content, they require high switching frequency along with various pulse width modulation (PWM) strategies. As the number of voltage levels increases, the harmonic content of output voltage waveform decreases significantly. Battery systems are affected by many factors, a key one being the cells unbalancing. Without the balancing system, the individual cell voltages will differ over time, battery pack capacity will decrease quickly. That will result in the failure of the total battery system. Thus cell balancing acts an important role on the battery life preserving. Different cell balancing methodologies have been proposed for battery pack. In this paper, the general structure of multi-level converter is to synthesize a near sinusoidal voltage from several levels of dc voltages. The operational principle of the proposed system is first described, and then, the design equation is derived. Simulation results are obtained for single phase 9-level inverter with battery balancing with MATLAB/Simu link.
