The power terminal frame is embedded in the front side of the frame or the inner side of the back side, wherein the signal terminal frame is embedded in the left side of the frame or the inner side of the right side.

Description

technical field [0001] The present invention relates to a power device, and more particularly to a power module which can be applied to various circuit structures and various voltages and has a larger current output range. Background technique [0002] Since MOSFET and IGBT power modules have a wide range of industrial applications, they are designed with different voltage and current levels. For example, the withstand voltage range of MOSFET modules can be from 60V to 600V, and the withstand voltage range of IGBT modules can be from 600V to 6500V. On the other hand, for power modules of the same withstand voltage level, the output current is also very different according to the size of the load. For example, for IGBT modules with a voltage level of 1200V, the output current range can be increased from 50 amps to over 1000 amps. Furthermore, for different applications, the design of MOSFET and IGBT modules has different circuit structures, such as single-tube, half-bridge,...
