提出了一种新的具有分离直流源的多电平电压源逆变器，用于高压、大功率应用，例如柔性交流输电系统（FACTS），包括静止无功发生（SVG）、电力线调节、串联补偿、移相、电压平衡、燃料电池和光伏公用事业系统接口，新型M电平逆变器由（M-1）/2个单相全桥组成，每个桥都有独立的直流电源。该逆变器可以产生几乎正弦波形的电压，只有一个时间的开关，每一个周期的电平数增加。它可以解决传统的基于变压器的多脉波逆变器的问题和多电平二极管箝位逆变器和多电平有源电容逆变器的问题。为了证明新逆变器的优越性，SVG系统采用新的逆变器拓扑进行了讨论，通过分析，仿真和实验。
A new multilevel voltage-source inverter with separate DC sources is proposed for high-voltage, high power applications, such as flexible AC transmission systems (FACTS) including static VAr generation (SVG), power line conditioning, series compensation, phase shifting, voltage balancing, fuel cell and photovoltaic utility systems interfacing, etc. The new M-level inverter consists of (M-1)/2 single phase full bridges in which each bridge has its own separate DC source. This inverter can generate almost sinusoidal waveform voltage with only one time switching per cycle as the number of levels increases. It can solve the problems of conventional transformer-based multipulse inverters and the problems of the multilevel diode-clamped inverter and the multilevel living capacitor inverter. To demonstrate the superiority of the new inverter, a SVG system using the new inverter topology is discussed through analysis, simulation and experiment.
