Title
High-Voltage-Input, Low-Voltage-Output, Series-Connected Converters With Uniform Voltage Distribution
Abstract
This paper presents a power system consisting of current-mode, shared-bus converters configured as Series-Input, Parallel-Output (SIPO). These current-mode commercial-off-the-shelf (COTS) dc-dc converters transform a 1kV system input voltage into a 5V output with up to 500 Watts of power. The SIPO power system provides for system expansion and preserves the standalone converter's efficiency of over 80%. Uniform input voltage distribution control improves power system reliability by distributing thermal stresses equally among the series-connected converters. Furthermore, robust system stability and uniform input voltage distribution among series-connected converters is realized without control conflict. A computer simulation and an experimental 1 kV 500 W prototype were successfully implemented to validate the uniform voltage distribution power converter architecture. © 2009 IEEE.
