Abstract
A power conversion system includes a shared output bus and a plurality of power conversion units coupled to the shared output bus. Each power conversion unit includes a power converter having a converter output coupled to the shared output bus and a delay generator that generates a start-up delay for the power converter if a pre-bias value of a bus voltage on the shared output bus is greater than a predefined threshold. Each power conversion unit also includes a voltage controller that controls the converter output subsequent to the start-up delay and maintains a current sourcing condition of the converter output during start-up of the power converter. The power conversion system also includes a load that is coupled to the shared output bus. A method of operating a power conversion unit is also provided.
