Zusammenfassung:	An inverter 54 for a computed tomography (CT) system 10 is provided. The inverter 54 includes a hybrid switch 64. The hybrid switch 64 includes a silicon carbide metal-oxide-semiconductor field-effect transistor (SiC MOSFET) portion 66, an insulated-gate bipolar transistor (IGBT) portion 68, a first gate 70 associated within the SiC MOSFET portion 66, and a second gate 72 associated with the IGBT portion 68. The SiC MOSFET portion 66 and the IGBT portion 68 of the hybrid switch 64 are configured to be independently controlled via the first gate 70 and the second gate 72.
