Vicor Power Supply Solutions for Open Architecture Standards

This case study discusses the implementation of Vicor's power supply solutions designed for migrating to open architecture standards, specifically CMOSS and SOSA, in power systems. The document outlines the challenges faced in powering software-defined radio cards, memory cards, and processor cards while minimizing power draw to avoid detection by radar-guided surface-to-air missiles. Key objectives included drawing minimal current when disabled, adhering to a 3U standard form factor, and enabling quick prototyping and implementation. Vicor's VPX solutions are highlighted for their time and cost efficiency, eliminating the need for complex discrete component designs. The case study details the benefits of a modified SOSA compliant 3U power supply, which reduces the heat signature of the vehicle when the systems are inactive. The document also describes the rugged, VITA62 SOSA compliant OpenVPX power supplies that provide high power density and reliability, customized with features to enhance stealth capabilities.
