摘要

本文提出了一种开关数量最少的九电平开关电容器逆变器(NLSCI)。近年来,开关电容器多电平逆变器(MLI)已成为最常见的逆变器拓扑结构之一。这些拟议的九电平开关电容器逆变器(NLSCI)不需要任何外部控制单元来控制电容器。因为电容器的充放电是由开关的开和关状态控制的。此外,通过采用较少的开关和直流电压源,建议的设计可产生更大的结果电压。此外,建议采用脉宽调制(PWM)方法来提高输出质量和电平质量。开关电容双输出多电平逆变器(SCMLI)结构的可行性和有效性已通过 MATLAB 仿真得到证实。

Nine level switched capacitor inverter with level shifted pulse width modulation approach
This article proposes a nine-level switched capacitor inverter (NLSCI) with a minimum number of switches. In recent years, switching capacitor (SC) multilevel inverters (MLIs) have become one of the most common inverter topologies. These proposed nine level switched capacitor inverter (NLSCI) do not deserve any external control unit for capacitor control. Since, the charging and discharging of the capacitors are controlled by the on and off states of switches. Furthermore, by employing fewer switches and DC voltage sources, the suggested design produces a greater amount of resultant voltage. Additionally, pulse width modulation (PWM) is recommended as a method to enhance output quality and power level quality. The switched-capacitor two-output multilevel inverter (SCMLI) structure's viability and effectiveness have been demonstrated using MATLAB simulation.
