This paper presents a low switching frequency, Selective Harmonic Elimination (SHE) modulation method which may be applied to a Cascaded H-Bridge Active Rectifier. The method is based on a decoupled scheme where the modulation index of each H-Bridge cell is controlled independently to enable complete control of power flow through the converter. The method… CONTINUE READING
