Abstract
A method and apparatus for operating quantized power converters in a phase staggered power sharing array is disclosed. The number, N, of active converters in the array is automatically determined. The converter operating at the highest frequency is determined and awarded driver status. The system operating frequency is set to approximately N times the highest converter operating frequency and synchronous phase staggered timing signals are sent to the remaining converters. A method and apparatus for detecting faults and automatically reconfiguring the array are disclosed.
