Single-Phase Cascaded Inverter Experimental Platform Design

This paper presents the design of a low-power single-phase NPC inverter experimental platform to fulfill the requirements of power electronics education and research. It details the platform's implementation, control strategies, and experimental validation. The hardware architecture integrates critical modules including the main power circuit, control circuitry, and sampling circuits, while the software system employs automatic code generation technology. Demonstrating platform functionality through Finite Control Set Model Predictive Control (FCS-MPC) implementation, experimental results verify both the system's operational performance and algorithm effectiveness. This platform serves as a practical tool for hands-on education and scientific investigation in power electronics, offering comprehensive support for theoretical verification and control strategy development.
