Compact Rack Power Supply for Submarine Combat Control

This technical report outlines a power supply solution designed for submarine combat control applications. The document describes the customer's challenge of needing a power supply in a 3U VPX packaging format to accommodate various power requirements while considering space constraints within the rack. The proposed solution involves using two DCM DC-DC Converter modules in parallel to deliver a high power 1200W, 12V rail, facilitating power sharing between the converters. The low profile of the design, achieved through conduction cooling, allows for a narrow power supply case width. The report details the dual-sided cooling capability of the DCM's ChiP packaging, which enhances thermal performance and reduces waste heat, enabling higher ambient operating temperatures. Additionally, the modularity and scalability of the solution support various supply configurations from a common base design, allowing for redundancy when needed. The document concludes with key specifications of the DCM DC-DC Converter modules, including input and output voltage ranges, output power, efficiency, and dimensions.
