<P>PROBLEM TO BE SOLVED: To provide a power module having a plurality of power devices, capable of achieving high reliability of a protective function, miniaturization and cost reduction. <P>SOLUTION: The power module 100 includes current detection sections 12, 22 that generate current detection signals DT1, DT2 taking a level corresponding to the magnitude of a main current running through two switching elements 10, 20. Driving control sections 13, 23 receive both of the current detection signals DT1, DT2, and detect generation of overcurrents of the switching elements 10, 20 to perform protection operation of the switching elements 10, 20, based on the level combination. <P>COPYRIGHT: (C)2012,JPO&INPIT |
