Abstract
An AC switching arrangement is provided with an energy transfer arrangement connected in parallel with a switching mechanism. The energy transfer arrangement comprises a capacitance arrangement and a diode arrangement. The switching mechanism normally closed in a first state, and on reception of a signal indicating the second state, the switching mechanism is arranged to open. When the switching mechanism is in the second state, the diode arrangement is arranged in each AC half cycle to enable energy (source energy, stored inductance energy, etc.) to transfer from the grid to the capacitance arrangement but to prevent energy transfer from the capacitance arrangement back to the grid.

1-48. (canceled)
An AC switching arrangement for connection to an AC grid, the AC switching arrangement comprising:
- a first grid terminal connectable to a first node in the AC grid and a second grid terminal connectable to a second node in the AC grid;
- a switching mechanism connected in series between the first grid terminal and the second grid terminal, wherein the first switching mechanism includes a first switch, and wherein the first switch is closed in a first state and open in a second state;
- an energy transfer arrangement connected in parallel with the first switch, the energy transfer arrangement comprising a capacitance arrangement and a diode arrangement;
- wherein, on reception of a signal indicating the second state, the switching mechanism is arranged to open the first switch;
- wherein, when the first switch is in the second state, the diode arrangement is arranged in each AC half cycle to enable energy to transfer from the AC grid to the capacitance arrangement but to prevent energy transfer from the capacitance arrangement back to the AC grid.
