A current controller for a grid-tied, cascade multilevel inverter

Abstract:

A cascade multilevel inverter is simulated and implemented to supply power to the grid from a set of 4 isolated batteries. The phase-shifted carrier PWM modulation strategy is employed in this article, increasing the frequency of the output current. A PI controller is applied to achieve a connection to the grid. Simulation results supplying current on phase, leading and lagging are shown, and experimental results validate the prototype built.
