Abstract

Multilevel inverters (MLIs) have become a favoured option for medium voltage and high power DC to AC conversion applications to assure high power level cascade type inverter which accepts multiple/single DC sources and offers combined AC output for appropriate voltage and frequency. MLIs provide various benefits over two-level inverters, including lower dv/dt, the capacity to handle greater voltage levels, a quasi-sinusoidal output waveform, and lower Total Harmonic Distortion (THD), among others. The biggest problem in adopting the MLI is the increasing number of switches and it's design. MLIs based on switched capacitors (SC) for boost-type DC-AC converters often demonstrate a trade-off among switch voltage rating and switch count. This work introduces a new 5-level(5L) SC inverter by adding a switched capacitor module into the usual 3L neutral point clamped inverter leg(NPC). The SC unit consists of one bidirectional switch and two capacitors capable of withstanding one-quarter of the DC voltage. When compared to typical 5L inverters, such as standard NPC and active NPC designs, the new approach in addition reduces the amount of switches but also shorten the topology. The proposed FLSCI has been examined by using several PWM techniques. The simulation and hardware results showed that the presented FLSCI is ideal for a broad variety of applications.

五电平SC逆变器减少开关计数和自平衡能力
多电平逆变器(mli)已成为中压和大功率直流到交流转换应用的首选,以确保高功率级联型逆变器接受多个/单个直流电源,并提供适当电压和频率的组合交流输出。与双电平逆变器相比,mli具有多种优势,包括更低的dv/dt、处理更高电压水平的能力、准正弦输出波形和更低的总谐波失真(THD)等。采用MLI最大的问题是不断增加的开关数量及其设计。基于开关电容(SC)的升压型DC-AC变换器的mli通常需要在开关电压额定值和开关计数之间进行权衡。这项工作介绍了一种新的5电平(5L) SC逆变器,通过在通常的3L中性点箝位逆变器腿(NPC)中添加开关电容模块。SC单元由一个双向开关和两个能够承受四分之一直流电压的电容器组成。与典型的5L逆变器(如标准NPC和有源NPC设计)相比,新方法除了减少开关数量外,还缩短了拓扑结构。所提出的FLSCI已经通过使用几种PWM技术进行了检查。仿真和硬件结果表明,所提出的FLSCI是各种应用的理想选择。
