Abstract:

The term solar smart inverter has become very important in the electronics industry. It is a combination of multi-level inverter and solar charging. Inverters are primarily classified as single level and multilevel inverters. Minimum harmonic distortion, reduced EMI generations are the major advantages of multilevel inverters as compared to single level inverters. Multilevel inverters can operate on various voltage levels and its applications, such as active power filters. By using sinusoidal pulse-width modulation (SPWM) control, within the inverters we can control the gain of inverters more effectively. One of the most forthright methods of describing voltage source modulation is a SPWM scheme that can be conceived by the intersection of a modulating signal with triangular carrier waveforms. In this paper, we have designed a Solar Multilevel Pulse Width Modulator inverter using SPWM and cascade 2H-bridge topology which increases the efficiency and reliability of the system.
