High power density power supply for next-generation radar applications utilizing emerging wide-bandap semiconductor devices

Next generation Naval warships utilize increasingly powerful and integrated radar systems, such as the next generation Air Missile Defense Radar (AMDR), for their versatile missions. The AMDR system combines a wide variety of functionalities, including: horizon search, missile communication and guidance, volume search, and ballistic missile defense and discrimination. While AMDR enhances critical mission capabilities, it is also expected to increase the power requirements of the ship's generation and distribution system. The required combination of high power density, high efficiency, and high input voltage rating of the required radar power supplies precludes the use of conventional Silicon power semiconductors and power topologies. As a result, the next-generation of radar power supply systems requires a new and revolutionary power electronics design that delivers superior speed, efficiency, and voltage capabilities to yield system level miniaturization. This Small Business Innovation Research Phase II project seeks to develop next-generation radar power supplies capable of high power (2.5 kW), high efficiency (>90%), and high input voltage (1000 V) which are compact (>200 W/in3) and require minimal output energy storage (
