Custom MIL-STD 901, 2000 Watt Power Supply Overview
Application: Custom Navy power supply to meet MIL-STD-901.
Project Abstract: This customer is working on a IRAD program for the next generation satcom terminal for the US Navy. The application called for a dual output, 2000 watt, ac to dc watt power that would meet MIL-STD-901, Grade A, Class I, Type A shock testing and MIL-STDs 461, 810 & 1399.
This customer’s application required the custom military power supply to be a self-contained, standalone. Since this is a Navy military program, this custom military power supply would need to be designed to meet related MIL-SPECs and MIL-STDs. Their basic power needs: 2000 watts, dual output, 24Vdc & 48Vdc which is not unusual or difficult from a design standpoint. The engineering challenge is the high shock requirement which requires additional structural enhancements to the internal components.
The first design objective was to design the power supply to withstand MIL-STD-901 extreme shock requiring securing of high mass components. Special strapping methods and supports were designed to eliminate component movement. Additionally, this design would be high-temp, military grade components to tolerate high temps. The second objective was to design a conduction cooled baseplate architecture. This would allow the power supply unit to be mounted to a heatsink or cold-plate mount.
