A motor drive apparatus has G groups (G>/=2) of m-phases inverter units and G groups (G>/=2) of m-phases AC windings for feeding through the m-phases inverter units to the m-phases AC windings and G groups (G>/=2) of DC power sources which are connected to G groups of the inverter units so as to form alternative series closed loops on the DC circuit. |
