A control circuitry (134) and a method for controlling a bi-directional switch (132) is provided. The bi-directional switch (132) having a control terminal (130) for receiving a control voltage (124) to control an on state and an off state of the bi-directional switch (132) and at least one semiconductor switch in a bi-directional main current path. The control circuitry (134) comprises an energy storage element (102), a coupling means (101) to couple the energy storage element (102) to a supply voltage to charge the energy storage element (102), and a control circuit (108) configured to receive power from the energy storage element (102) and pendent of the supply voltage when the emergency storage element (102) is not coupled to the supply voltage. The coupling means (101) is configured for only coupling the energy storage element (102) to the supply voltage when the bi-directional switch (132) is in the off state.
A control circuitry (134, 1102, 1204, 1304) for controlling a bi-directional switch (132, 212, 220) having a control terminal (130) for receiving a control voltage to control an on state and an off state of the bi-directional (132, 212, 220) and at least one semiconductor switch (143, M1, M2, M10, M20, 1110, 1206, 1308) in a bi-directional main current path (144, 1112), the control circuitry (134, 1102, 1204, 1304) comprises:
A method (1400) of controlling a bi-directional switch having a control terminal for receiving a control voltage to control an on and off state of the bi-directional switch and at least one semiconductor switch in a bi-directional main current path,
