  • Method and apparatus for pre-charge control of VSI
    Patent number: 6275392
    Abstract: A method and apparatus for automatically selecting and employing different DC link pre-charge levels dependent upon different sources providing power to a power conditioning system wherein the different sources are characterized by different source inductances, the apparatus including a source control that selects a first pre-charge level when a utility supply provides power to the system and selects a relatively lower pre-charge level when a generator supply provides power to the system thereby reducing the possibility of inverter disablement due to DC link voltage dips.
