SWITCHING MODULE INCLUDING SWITCHING ELEMENT CONTROLLED TO BE TURNED OFF WHEN CONDUCTION FAILURE IS DETECTED
First Claim
1. A switching module comprising:
- a switching element having a control terminal, electrically connected to a first conduction path including a reference terminal, the first conduction path being opened and closed by controlling the switching element to be ON and OFF, the switching element being controlled in response to a voltage difference between the reference terminal and the control terminal;
determining means for determining whether or not a conduction failure has occurred between the control terminal and an outside the switching module; and
reducing means for reducing an absolute value of the voltage difference when the determining means determines that the conduction failure has occurred, so as to forcibly turn OFF the switching element.

Abstract
A switching module includes a switching element having a control terminal, electrically connected to a first conduction path including a reference terminal, to be opened and closed by controlling the switching element to be ON and OFF. The switching element is controlled in response to a voltage difference between the reference terminal and the control terminal. Moreover, the switching module includes determining unit that determines whether or not a conduction failure has been occurred between the control terminal and an outside the switching module; and reducing unit that reduces an absolute value of the voltage difference when the determining unit determines that the conduction failure has occurred, so as to forcibly turn OFF the switching element.
