Abstract
This paper addresses the study, design and implementation of a multilevel inverter aimed to operate with the Ecuador’s most commonly used electrical distribution schemes, being able to be connected to the grid without a transformer. The implemented control allows to revert the power flow if it is required (e.g. charge a battery bank). The paper shows the different steps for the design, as well as simulations and preliminary experimental results.
