A switching module, including a first self-turn-off device, a second self-turn-off device connected in series with the first self-turn-off device, a first diode connected in antiparallel with the first self-turn-off device, a second diode connected in antiparallel with the second self-turn-off device, and a third diode with its cathode connected to a connecting point of the first and second self-turn-off devices. The switching module further includes a first external terminal connected to a positive side terminal of the first self-turn-off device, a second external terminal connected to a negative side terminal of the second self-turn-off device, a third external terminal connected to an anode of the third diode, a first external control terminal connected to a control signal terminal of the first self-turn-off device, and a second external control terminal connected to a control signal terminal of the second self-turn-off device.
