“…Moreover, the stress caused by voltage on power switching devices is lower, and the system can be operated with a lower switching frequency [11]. Currently, there are three conventional categories of inverter topologies: diode‐clamped [12–14] inverters, flying capacitor inverters [15] and cascaded inverters [16–19]. Among them, the cascaded H‐bridge multilevel inverters are the most popular because of their modular structure and fewer peripheral hardware such as clamp diodes or capacitors [20].…”

“…If the interleaved PWM is applied to the parallel converter, the occurrence of SFCC is even worse. This SFCC can be reduced by applying modified PWM techniques [4][5][6].…”

“…Previous studies have analyzed ZSCC about 1 st and 3 rd order harmonics [9,10] or SFCC [4][5][6]. The PR controller for only the 3 rd harmonics is designed and applied without a clear basis for ZSCC caused under the unbalanced load conditions.…”

“…Существуют работы, в которых рассматривается проблема улучшения качества формируемого фазного тока многоуровневыми структурами в параллельном включении [16,17]. В работе [17] авторы исследуют зависимость величины циркуляционных токов и коэффициента гармоник фазного тока для различных способов модуляции со сдвигом опорных сигналов: phase disposition (PD), alternative phase opposite disposition (APOD) и phase opposite disposition (POD). В ходе проведения исследования авторы приходят к выводу, что в случае применения способа модуляции APOD протекающие между двумя трехуровневыми ПП в параллельном включении циркуляционные токи удается снизить на 2/3 по сравнению со способом модуляции PD.…”
