Abstract
In order to provide semiconductor device modules which are capable of solving problems caused by the presence of the control board, and facilitating electric connection between power semiconductor elements and main circuit terminals and lightening restrictions on the number and layout of the power semiconductor elements, a control emitter relay terminal, a gate relay terminal, and a relay terminal are connected to a control board disposed above an edge portion of the semiconductor device module. The control board has control circuitry and elements for controlling operations of an IGBT device and a diode device, and also has a control emitter interconnection pattern to which the control emitter relay terminal is connected and a gate interconnection pattern to which the gate relay terminal is connected, where these interconnection patterns are connected to control circuitry.
