This paper proposes an AC voltage sensorless simple four-quadrant structure which can be used in cascade multilevel inverter. The AC input voltages of every cell in combination with the AC filter inductors can be assumed to be quantities related to a virtual AC motor. The AC input voltages are induced by a virtual air-gap flux (VF). Using VF for instantaneous powers estimation, the AC input voltages...
