Radiation-hardened DC-DC converters to control power in space electronics introduced by VPT Power

BLACKSBURG, Va. – VPT Inc. in Blacksburg, Va., is introducing the SGRB series of space-qualified DC-DC converters for a variety of satellites, manned spacecraft, and other space applications.

Using advanced gallium nitride (GaN) technology, the SGRB offers efficiency to 95 percent, as well as radiation tolerance.

The power electronics device offers fixed-frequency reduced voltage switching topology for low input and output noise, making it suitable for use in telecommunications systems.

Designed for applications facing the harsh radiation environments of space, the SGRB series has been characterized to total ionizing dose of 100 krad(Si), including enhanced low dose rate sensitivity, and single event effects performance to 85 MeV/mg/cm2.

The SGRB series features an integrated electromagnetic interference filter, 100-volt input and 28-volt, 400-Watt output, and is rated for full power operation in temperatures from -35 85 degrees Celsius.

These DC-DC converters "dramatically increases the power supply efficiency. This, in turn, greatly reduces the system size, weight, and cost," says Jeremy Ferrell, VPT's director of engineering. VPT is reviewing customer requests for custom orders of the SGRB series.
