Pumped 2-Phase Cooling as an Enabler for a Modular, Medium- Voltage, Solid-State Circuit Breaker
Nov. 4, 2021
DC distribution systems have been proposed for marine vessels, as they have several potential advantages over AC systems.
This paper introduces a pumped 2-phase (P2P) cooling system as an enabler for a high power density SSCB for protection in a 12 kVDC distribution system. This cooling system provides isothermal operation of paralleled semiconductors for high current operation with good current sharing. Additionally, the use of a dielectric refrigerant in the cooling system allows for series-connected semiconductors with electrically isolated heat sinks, simplifying insulation coordination between series-connected devices.
