摘要：
A control circuitry and a method for controlling a bi-directional switch is provided. The bi-directional switch having a control terminal for receiving a control voltage to control an on state and an off state of the bi-directional switch and at least one semiconductor switch in a bi-directional main current path. The control circuitry comprises an energy storage element, a coupling means to couple the energy storage element to a supply voltage to charge the energy storage element, and a control circuit configured to receive power from the energy storage element and configured to supply the control voltage having a voltage level being independent of the supply voltage when the energy storage element is not coupled to the supply voltage. The coupling means is configured for only coupling the energy storage element to the supply voltage when the bi-directional switch is in the off state.
