Abstract

The invention provides a power module for an integrated control circuit. The power module comprises a power substrate, a power device which is arranged on the power substrate, at least one control substrate which carries a control circuit and is electrically connected with the power substrate and is arranged on one side, which is provided with the power device, of the power substrate at an inclination angle, wherein the inclination angle is greater than or equal to 45 degrees and less than or equal to 135 degrees. According to the power module provided by the invention, except that the connection between the control substrate and the power substrate occupies the horizontal area of the module, only the power substrate occupies the horizontal area of the module; the horizontal occupied area of the power module is effectively reduced; and the power density of the power module is improved.

Description

technical field [0001] The invention relates to a power module, in particular to a high power density power module integrated with a control circuit. Background technique [0002] An existing power module integrated with a drive control circuit generally includes a power device, a power substrate carrying the power device, a control device constituting the drive control circuit, and a control substrate carrying the drive control circuit. Figure 1A-1B They are respectively schematic diagrams of two existing power modules integrated with drive control circuits. Such as Figure 1A As shown, the power device 11 is soldered to the power substrate 12 by soldering. The power device 11 is, for example, a power semiconductor chip, and the power substrate 12 is, for example, a Directed Bonded Copper (DBC) substrate. The control device 13 includes, for example: a driving device for controlling the power device 11 , a resistor, a capacitor and some other devices required for driving,...
