Abstract: Power supplies for future Navy active phased array radar systems require significantly advanced technologies to provide higher power density, faster transient response, lower output capacitance, and lower cost and noise than present commercial technologies. The technical challenges include thickness reduction to less than 10mm, conversion efficiency greater than 90%, and thermal control at base plate temperature 70�C. Custom Manufacturing & Engineering (CME) proposes to design and develop an isolated DC/DC converter for pulsed current loads of 300V input / 28V output, output power greater than 1kW and power density higher than 200W/in3 with response time and settling time each within 10ms, and overshoot less than 4%. To reach these goals, CME will identify new and innovative research and development approaches by theoretical analysis, computer simulations, and sample testing of currently available commercial off-the-shelf (COTS) components that will lead to an effective modified COTS design. CME has a long history and extensive experience in pursuing power supply advance technologies with Navy applications. The company's design experience includes rugged military power supplies, innovative switching topology, and a digital control loop design that are adaptable for this project.
Benefits: Equipped with this innovative, high performance power supply, future Navy active array radar systems will achieve significant reduction in antenna weight, size, and cost. Potential applications include emerging and planned ships such as DD(X), CG(X), etc. The power supply will also have the immediate advantages for US, joint, and international ground based active array radar systems such as G/ATOR and MEADS. Commercial applications include phased array communication antenna, communications equipment, and computer systems. The innovative power technologies from this project can be quickly adopted by military and commercial markets that require high density DC/DC converters.
