Patent ID: 7242113

Claim:
A power semiconductor device, comprising: plural power semiconductor elements which have a control electrode and a first and a second current electrodes, respectively, and said first current electrodes are connected with each other and said second current electrodes are connected with each other, respectively; at least one detecting part detecting information corresponding to an operating condition of said plural power semiconductor elements; and a control part controlling said plural power semiconductor elements, wherein said control part repeats a regional control operation to operate a first group of said plural power semiconductor elements by providing a first input signal for each of said control electrodes of said first group, and to operate a second group of said plural power semiconductor elements by providing a second input signal for each of said control electrodes of the second group after an operation of said first group is finished, said detecting part provides said information for said control part, and said control part selects said first group and said second group of said plural power semiconductor elements being made to operate when said regional control operation is performed on the basis of said information.
