Abstract
A radiation hardened active power transformer includes an active compensator on a primary side of a transformer. The transformer steps up an input voltage to an output voltage. The active compensator controls a reactive power of the output voltage. The active compensator includes wide band-gap transistors which radiation harden the active compensator to resist ionizing radiation.
