Abstract
Embodiments of a transistor control device for controlling a bi-directional power transistor are disclosed. In an embodiment, a transistor control device for controlling a bi-directional power transistor includes a resistor connectable to a body terminal of the bi-directional power transistor and a transistor body switch circuit connectable to the resistor, to a drain terminal of the bi-directional power transistor, and to a source terminal of the bi-directional power transistor. The transistor body switch circuit includes switch devices and alternating current (AC) capacitive voltage dividers connected to control terminals of the switch devices. The AC capacitive voltage dividers are configured to control the switch devices to switch a voltage of the body terminal of the bi-directional power transistor as a function of a voltage between the drain terminal of the bi-directional power transistor and the source terminal of the bi-directional power transistor.
