This is an ideal DC/AC converter.
The polyphase converter is characterized by:
vDC*iDC + v1*i1 + v2*i2 + v3*i3 = 0vDCRef is applied to the DC side without limitationsphi influences the AC reactive power as shown in the figure below,
where underlined voltages and currents represent complex voltage and current phasorsphi may supply a capacitive load (see figure below)phi may supply an inductive load
