This paper introduces a new 60[Formula: see text] Flat PWM Technique for Single-Source Switched-Capacitor(SC) Multilevel Inverter with Quadruple Boost (60FP-MLI-QB) and Enhanced Output. The proposed design generates nine output levels with lower switching losses using the 60[Formula: see text] Flat PWM (60FP) Technique. Furthermore, this technique increases the voltage gain enhancement while flattening the sine wave at its peak. The driven inverter topology includes 11 switches, two capacitors, and a diode, with each levels circuit connected through six or five switches. The performance of the proposed 60FP-MLI-QB is tested through simulation and hardware experiments under various dynamic conditions, showing its flexibility and superiority compared to similar configurations. Moreover, the paper presents a harmonic minimization technique through various FP methods by modifying the sinusoidal modulation reference.
本文介绍了一种用于具有四重升压功能的单源开关电容（SC）多电平逆变器（60FP-MLI-QB）和增强输出的新型60°扁平脉宽调制（PWM）技术。所提出的设计采用60°扁平PWM（60FP）技术，以较低的开关损耗产生九个输出电平。此外，该技术在使正弦波峰值变平的同时提高了电压增益。驱动逆变器拓扑结构包括11个开关、两个电容器和一个二极管，每个电平电路通过六个或五个开关连接。通过在各种动态条件下的仿真和硬件实验测试了所提出的60FP-MLI-QB的性能，表明其与类似配置相比具有灵活性和优越性。此外，本文通过修改正弦调制参考，提出了一种通过各种FP方法实现谐波最小化的技术。
