SBIR-STTR Award

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.
