ALEXANDRIA, Va., Nov. 6 -- United States Patent no. 12,463,638, issued on Nov. 4, was assigned to Efficient Power Conversion Corp. (El Segundo, Calif.).

"Driver circuit for GaN FET solid state relay" was invented by Michael A. de Rooij (Playa Vista, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A driver circuit for a solid-state relay which includes a split power supply. The positive supply of the split power supply provides a voltage for application to the gate of a power FET for supplying power to a load. The negative supply of the split power supply provides a negative voltage for turning off a control transistor. The control transistor prevents the power FET from conducting power to the load when...
