Abstract
A power semiconductor module with a bridge circuit is housed in a common case. The module includes a plurality of element chips separated into groups for semiconductor elements, a plurality of drive chips, and a signal processing chip formed as an integrated circuit. Each drive chip is formed as an integrated drive circuit and is connected to each semiconductor element to correspond thereto. Each drive chip operates at a potential corresponding to each semiconductor element. The signal processing chip is connected to the drive chips to be shared commonly by the drive chips. The signal processing chip processes signals associated with the drive chips in such a way that the signals are compatible with the potentials of the drive chips. Cost and performance of the module is improved.
