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.

U S Army tactical vehicles are equipped with a wide range of electrical and electronic equipment to support a variety of missions. This equipment typically requires AC input power with varying voltage, power and phasing requirements. Presently, separate inverters with different voltage, power, and phase ratings are necessary to power the equipment, which imposes maintenance and support problems during field deployments. Avionic Instruments Inc. has developed a scalable inverter system that operates from 28V vehicular power and provides outputs that can easily be configured for a variety of load requirements.

Cockpit instrument lamp dimmers are specialized DC-DC, AC-DC, or DC-AC converters which provide controlled power to incandescent, EL, or LED instrument and cabin lights. These dimmers are controlled by a command voltage, a programming resistor, a potentiometer, or a combination of these methods to provide controlled and conditioned power to the aircraft lighting loads. In addition to cockpit instrument uses, these lamp controllers can be used for cabin lighting, task lighting, mood lighting, and marker/signal lighting.
