Abstract
The aim of this paper is to introduce a novel microinverter design that is based on the DC/DC converter, Buck. This structure is intended to provide a sinusoidal voltage to low-power autonomous loads embedded in vehicles, which require excellent waveform quality. In the first part, the paper presents the new topology, its modeling, and the control strategies employed. Two control strategies are discussed, including the classical control with a PI regulator and the sliding mode control with the step function. The dimensioning is carried out using the Ziegler-Nichols method, and the stability is ensured using the Lyapunov method. In the second part, the paper comments on the results obtained from different simulations in terms of harmonic distortion (THD), efficiency and control robustness with different sources, such as battery and photovoltaic panel.
