PURPOSE: By being connected with the restoration voltage to three phase power source by using the switching unit the restoration voltage supply power supply unit minimizes the energy consumption. CONSTITUTION: The regeneration power supply unit(110) is however and parallel connected the plus of the DC link to the minus platform. The restoration voltage is inputted to the regeneration power supply unit. Supplies three phase power source the inputted restoration voltage is switched to the switching unit(120) is the regeneration power supply unit. The controller(130) supplies the restoration voltage to three phase power source by driving the switching unit. |
