Abstract

A semiconductor switching arrangement includes a normally on semiconductor component of a first conduction type and a normally off semiconductor component of a second conduction type which is the complement of the first conduction type. A load path of the normally off semiconductor component is connected in series with the load path of the normally on semiconductor component. A first actuation circuit connected between the control connection of the normally on semiconductor component and a load path connection of the normally on semiconductor component. The load path connection of the normally on semiconductor component is arranged between the normally on and normally off semiconductor components. A second actuation circuit is connected between the control connection of the normally off semiconductor component and a load path connection of the normally off semiconductor component. The load path connection of the normally off semiconductor component is arranged between the normally on and normally off semiconductor components.
