The power conversion system, a method to mitigate the voltage of the motor drive and limit the reverse rotation of a motor load, and medium readable by computer executable instructions

摘要

Power conversion system, method for slowing down sobretensao motor drive and limit the reverse rotation of a motor load, and computer readable medium with instructions executu00e3veis are disclosed apparatus and methods to slow down the sobretensao and limit the speed re Versas engine for the events of power loss of the motor drive.In a first circuit of power dissipau00e7ao is enabled at the exit of the motor drive to limit the reverse rotation. A load.Do the motor driven when power motor drive is lost, and a second circuit of power dissipation in a circuit of the DC bus is used to slow down the tensions surpluses after the restoration of power motor drive
