Abstract:
1. A semiconductor device, comprising a semiconductor module wherein a plurality of semiconductor circuits on which are mounted one or more semiconductor chips, each having a gate terminal and a gate resistor connected to the gate terminal, are disposed in parallel, wherein a plurality of the semiconductor modules are disposed above a cooling body so that an array direction of the semiconductor modules is a direction following a refrigerant flow, at least one temperature detecting resistor is disposed in each semiconductor module, and a semiconductor module positioned on an upstream side of the refrigerant flow and a semiconductor module positioned on a downstream side of the refrigerant flow are such that a gate signal is supplied via a temperature detecting resistor of the semiconductor module positioned on the downstream side of the refrigerant flow to a gate signal input terminal of the semiconductor module positioned on the upstream side of the refrigerant flow, while a gate signal is supplied via a temperature detecting resistor of the semiconductor module positioned on the upstream side of the refrigerant flow to a gate signal input terminal of the semiconductor module positioned on the downstream side of the refrigerant flow.
