Solar inverter has entered the market, where it is a combination of multilevel, a multi monitoring transformer, and with a solar charger. Although most are single-level inverters, others are multi ported. This is the primary benefit of multilevel inverters as opposed to single level ones: minimum harmonic distortion, lower EMI/RFI the Multilevel inverters can be set to run on any voltage between 115 and 230VAC. Sinusoidal and trapezoidal implementations of active control have different waveforms, which can be implemented with different multi-stage inverters. by adding PWM power, we can optimize the benefit of the inverters. The most straightforward way to simulate multivalent DC sources with modulations is to intersect the modulating signal with a triangular-shaped carrier waveform. in this article, we are creating a microcontroller based Solar Multivel Pulse Width Modulator utilizing cascade H bridge topology. We are also implementing MPT to enhance our overall performance. We will use the capacity of the full duration of the day to capture the greatest amount of sunshine during the day.
