Abstract
PURPOSE:To extend a speed control range easily by newly adding a converter and a transformer to an existing apparatus in order to extend the speed control range. CONSTITUTION:The converter 7 and the transformer 6 for dropping voltage are mounted in order to extend the speed control range. That is, the secondary side of an induction motor 1 is connected to the converter 7 while being connected to the converter 2 through the transformer 6 for dropping voltage. The output side of the converter 7 is connected to an inverter 4 through a DC reactor 3, and the output side of the converter 2 is connected to the output side of the oonverter 7. When high speed, the secondary power of the induction motor 1 is recovered to the power supply side through the converter 7, the DC reactor 3, the inverter 4 and the transformer 5 for power inversion. At low speed, the secondary power of the induction motor 1 is recovered to the power supply side through the converter 2, the DC reactor 3, the inverter 4 and the transformer 5 for power inversion.
