This paper presents the Integrated Power Distribution Unit (IPDU) concept, which brings together major electric power Conversion, Distribution, Management, and Protection (CDMP) functions in a single lightweight LRU. The IPDU enables CDMP functionality to be physically located at points-of-use nodes, while maintaining unified control among the several IPDUs used in an Electric Power System. IPDU functions include input power quality sensing, power conversion (Inverter, TRU, Frequency Converter, DC-DC Converter), power management (AC and DC SSPCs and Hybrid Contactors), and a control function consisting of a databus R/T, DSP control core, and a voltage-frequency-current sensor suite. The IPDU is currently being applied as a major electrical power system element within a new aircraft dual channel EPS.The three major goals of the IPDU design are Improved power management functionality (fully observable system), enhanced reliability, and reduced size and weight.
