Многоуровневый каскадный преобразователь частоты с силовым последовательным активным фильтром

Abstract

The scheme of the multilevel cascade converter of a frequency which each phase contains four single-phase inverters of a voltage at the attitude of voltages of their sources 3:3:3:1 is considered. Thus of the inverter with a greater voltage form a preset value of a voltage with use of multilevel pulse-width modulation, and the inverter with the minimal voltage is used as the power consecutive active filter, ful-filling a voltage of a mistake.
