<P>PROBLEM TO BE SOLVED: To provide a motor circuit and a motor control method for stabilizing an input voltage of an inverter. <P>SOLUTION: Capacitors C1, C2 are connected to the inverters INV1, INV2, respectively, and the capacitors C1, C2 are connected in series to each other. Outputs of the inverters INV1, INV2 are connected to stator coil ends of motors M1, M2, respectively, and a battery B is connected to a neutral point between the motors M1, M2. By controlling switchings of the inverters INV1, INV2, a connection relation between the battery B and the capacitors C1, C2 can arbitrarily be controlled, and then a current of the battery B and voltages of the capacitors C1, C2 are controlled, thus allowing input voltages of the inverters INV1, INV2 to properly be controlled. <P>COPYRIGHT: (C)2004,JPO |
