1) The document describes a simulation of a 3-phase grid-connected photovoltaic inverter system using hysteresis current control.
2) It uses a two-stage conversion process with a boost converter to maximize solar panel output and regulate the DC bus voltage, followed by an inverter with hysteresis current control to generate AC power for the grid.
3) Simulation results show the inverter is able to generate sinusoidal voltage and current waveforms that are synchronized to the grid, with total harmonic distortion below 5% using hysteresis current control.
