The fundamental phase shift compensation scheme in a digital-controlled VIENNA rectifier with variable carrier-fundamental frequency ratio under unbalanced grid conditions

In the DC power distribution systems, One-cycle control (OCC) based three-phase VIENNA rectifiers achieves high power factor (PF) easily. However, under unbalanced grid conditions, the fundamental phase shift between the input current and corresponding phase voltage obviously deteriorates PF, especi...
