  • Patent number: 6876171
    Abstract: A driving apparatus of a three-phase induction motor includes: a three-phase power supply unit for supplying three-phase power; a rectifier for rectifying the three phase voltage supplied from the three phase power supply unit; a voltage reducing unit for reducing a DC voltage generated from the rectifier and outputting a stabilized DC voltage; and an inverter unit for varying the DC voltage outputted from the voltage reducing unit to a three-phase AC voltage and driving a three-phase induction motor. A power-factor degradation generated during supplying a DC voltage to the inverter to drive the three-phase induction motor is prevented, a harmonic wave is removed, and because a high-priced inverter component is not necessary, its relevant expense is reduced.

  • Publication number: 20010009504
    Abstract: A one system module in which a ceramic PCB and an epoxy PCB are disposed inside a module body and a power element and a signal element are respectively mounted at the upper portion of each PCB, wherein a groove is made at the lower side surface and at the middle side surface of the module body to support the ceramic PCB and the epoxy PCB formed in a two-story structure, and a power pin for receiving a power signal from an external source is mounted on the ceramic PCB and a signal pin for receiving various signals from an external source is mounted on the epoxy PCB. With this one system module, the ceramic PCB and the epoxy PCB can be firmly supported by the groove made on the module body. And, since the power pin and the signal pin are separately disposed on the two PCBs, use of the socket is reduced, so that the area utility of the PCB is increased as well as acquiring a compact module.
