1500 Watt Custom Military Power Supply Overview
Application: Custom 1500 watt military power supply for helicopter application.
Project Abstract: This customer’s application required the custom military power supply to be a self-contained, chassis mounting unit for attachment on to the frame of the helicopter. As wit all military programs, this custom military power supply would need to be designed to meet related MIL-SPECs and MIL-STD-461, 702, 810, and 1275. The system being powered by this supply had a maximum draw of 1500 watts and required output voltages of 28Vdc and 5Vdc. The engineering challenge is designing the supply to operate in high ambient temperature environments and be able to withstand extreme shock and vibration conditions.
The first design objective was to construct the 1500 input and output sections to meet the high temp demands by utilizing a high efficiency rectifier and dc output section. All of the components used for this design would be high-temp, military grade to withstand high temperature operation. Part of this design effort included integrating a baseplate architecture to provide the conduction cooling, allowing the custom 1500 watt military power supply to be cooled to the mounting structure.
