Patent abstract

A hybrid semiconductor bipolar switch in which a normally-on high-voltage wide-bandgap semiconductor bipolar switch and a normally-off field effect transistor are connected in a cascode (Baliga-pair) configuration. The switch may be constructed as a stacked hybrid device where a discrete transistor is bonded on top of a bipolar switch. Power systems may use plural switches paired with anti-parallel diodes.
