Radiation-hardened DC-DC converter for power electronics applications in spacecraft introduced by VPT
BLACKSBURG, Va. – VPT, Inc., a HEICO company in Blacksburg, Va., is introducing the radiation-hardened SGRB12028S 120 volt DC-DC converter power supply for a variety of high-power space payload or bus applications.
Using advanced EPC Space gallium nitride (GaN) technology, the SGRB12028S is capable of 95 percent efficiency, and offers a fixed-frequency reduced-voltage switching topology for low input and output noise.
Designed for applications facing the harsh radiation environments of space, the SGRB series space-rated DC-DC converter has been characterized to total ionizing dose (TID) of 100 kilorads of radiation, including low dose rate and single-event effects performance to 85 MeV/mg/cm2.
The SGRB series features an integrated electromagnetic interference filter, 120-volt input and 28-volt , 400-Watt output, and is rated for full power operation at temperatures from -35 to 85 degrees Celsius.
"The SGRB product is a great building block to both 100-volt and 120-volt space power systems," says John Evans, engineering manager at VPT. For more information contact VPT online at www.vptpower.com.
