  • Publication number: 20210265993
    Abstract: A control system includes a control unit. When turning a bidirectional switch element ON, the control unit controls the bidirectional switch element to cause a time lag between a first timing and a second timing.

The one gate electrode is associated with one source electrode selected from a first source electrode and a second source electrode and having a lower potential than the other source electrode. The second timing is a timing when a voltage equal to or higher than a threshold voltage is applied to the other gate electrode associated with the other source electrode having a higher potential than the one source electrode.
