Simulation of a double-stage micro-inverter for grid-connected photovoltaic modules

Abstract

In this work, the performance of a double-stage micro-inverter using the adaptive incremental conductance (AIC) algorithm for grid-connected photovoltaic (PV) modules is evaluated by means of a Simulink model. We observe the response of the micro-inverter under transients of solar irradiance and under static conditions. We show that Maximum Power Point Tracking (MPPT) and conversion efficiencies above 98% can be expected.
