Abstract:
1. A power inverter comprising: a reference line operably provided with a reference potential; a supply line operably provided with a DC supply voltage with respect to the reference potential, the supply line being connected to a first terminal of a DC voltage supply and the reference line being directly connected to a second terminal of a DC voltage supply; a first half bridge comprising a high-side switch and a low-side switch, the high-side switch coupled between the supply line and a middle tap of the half bridge and the low-side switch directly connected between the middle tap and the reference line; wherein the low-side switch is formed by a normally-on silicon carbide (SiC) junction field effect transistor (JFET); and wherein the high-side switch is formed by a series circuit of a normally-on SiC JFET and a normally-off metal oxide field effect transistor (MOSFET).
