Abstract
According to an embodiment, a solid-state bidirectional switch includes a first and a second power field-effect transistor electrically connected anti-serial with each other. Each of the first and second power field-effect transistors includes a source region, a drain region, a body region forming a pn-junction with the source region and having an inversion channel region, a gate terminal, a drift region between the body region and the drain region and having an accumulation channel region, and a drift control region adjacent to the accumulation channel region. The accumulation channel region is controllable through the drift control region. The solid-state bidirectional switch further includes a controller connected with the gate terminals of the first and second power field-effect transistors.
