Abstract
A controller controls multiple parallel-coupled power transistors. A correction amount calculation unit generates a reference value based on multiple detection values, each of which has a correlation with the switching loss of corresponding one of the multiple power transistors, and generates multiple correction amounts such that the multiple detection values approach the reference value. A gate signal generating unit generates multiple gate signals based on a control instruction and the multiple correction amounts.
