Abstract
A body-control-device for a bi-directional transistor, said bi-directional transistor having a first-transistor-channel-terminal, a second-transistor-channel-terminal, a transistor-control-terminal and a transistor-body-terminal. The body-control-device comprises a body-control-terminal connectable to the transistor-body-terminal of the bi-directional transistor, a first-body-channel-terminal connectable to the first-transistor-channel-terminal of the bi-directional transistor, a second-body-channel-terminal connectable to the second-transistor-channel-terminal of the bi-directional transistor, a negative-voltage-source and a switching-circuit configured to selectively provide an offset-first-circuit-path between the first-body-channel-terminal and the body-control-terminal, wherein the offset-first-circuit-path includes the negative-voltage-source such that it provides a negative voltage bias between the body-control-terminal and the first-body-channel-terminal.
