Abstract:

This paper presents the comparison of two modulated model predictive control (M2PC) strategies (the classical M2PC approach, and the M2PC with optimized overmodulation) applied to a three-phase three-level voltage source inverter (3Ph-3L-VSI). The control strategies are tested under various scenarios: no-load, a linear load connection, and a nonlinear load connection. Although each algorithm has its advantages, simulations show that the overmodulated version presents a substantially better performance than the classical version since the classical M2PC creates gaps between switching regions, making rough transitions between them. In contrast, the overmodulation version can produce a continuous transition between those regions, resulting in lower THD and control effort.
