【 摘 要 】
A novel Z-source three-level inverter based on coupled inductors is proposed. The two inductors in traditional Z-source impedance network are replaced by two coupled inductors. The operating principle is described and the equations of boost factor and voltage stresses are deduced. Comparisons are made with other Z-source three-level inverters, especially the multicell switched inductor Z-source three-level inverter. The two topologies have same boost factor if a specific condition is met, but the proposed inverter uses less components and therefore the reliability is improved. SVPWM method for conventional three-level NPC inverter is easy to apply to the novel inverter after a simple modification. Simulations are conducted to verify the theoretical analysis.
