SWITCHING DEVICE

摘要

A switching device according to the present invention comprises: a plurality of semiconductor elements connected mutually in parallel; and a drive circuit for outputting control signals for switching the ON and OFF times for the semiconductor elements in coordination with each other. For at least one semiconductor element, the drive circuit sets an off-timing for switching from on to off and/or an on-timing for switching from off to on so as to be different from that of the other semiconductor element.
