Abstract:
A switchgear cell having a group of connection is disclosed, with the group of connection having a first and a second controllable bidirectional power semiconductor switch and a capacitor. In order to reduce the stored electrical energy and to save space, the group of connection can have a third, fourth, fifth and sixth controllable bidirectional power semiconductor switch and the first controllable bidirectional power semiconductor switch can be connected back-to-back in series with the second controllable bidirectional power semiconductor switch, the third controllable bidirectional power semiconductor switch can be connected back-to-back in series with the fourth controllable bidirectional power semiconductor switch, the capacitor can be connected to the connection point of the first controllable bidirectional power semiconductor switch to the second controllable bidirectional power semiconductor switch and to the connection point of the third controllable bidirectional power semiconductor switch) to the fourth controllable bidirectional power semiconductor switch, the fifth controllable bidirectional power semiconductor switch can be connected to the connection point of the first controllable bidirectional power semiconductor switch to the second controllable bidirectional power semiconductor switch, and to the fourth controllable bidirectional power semiconductor switch, and the sixth controllable bidirectional power semiconductor switch can be connected to the connection point of the third controllable bidirectional power semiconductor switch to the fourth controllable bidirectional power semiconductor switch and to the second controllable bidirectional power semiconductor switch.
