Abstract

A power module according to an embodiment of the present invention comprises: a first substrate having metal plates formed on one surface thereof; a second substrate spaced apart from the first substrate and having metal plates formed on one surface thereof facing the metal plates of the first substrate; a plurality of power elements disposed between the first substrate and the second substrate; afirst electrode formed on the first surface of each of the plurality of power elements; and a second electrode formed on the second surface of each of the plurality of power elements, wherein the plurality of power elements comprise a first power element in which the first electrode is bonded to the metal plates of the second substrate; and a second power element in which the first electrode is bonded to the metal plates of the first substrate.

Description

technical field [0001] The invention relates to a double-sided cooling type power module and a manufacturing method thereof, which are installed in environment-friendly vehicles such as electric vehicles, hybrid vehicles, and fuel cell vehicles, and household appliances such as air conditioners. Background technique [0002] Generally, a motor can be provided as a driving unit in an electric vehicle, a hybrid vehicle, a fuel cell vehicle and other environment-friendly vehicles, or an air conditioner and other household appliances. Such a motor may be driven by a three-phase current delivered through a power cable from an inverter that converts a DC voltage into a three-phase voltage through a PWM (pulse width modulation) signal of a controller. [0003] The inverter may be provided with a power element that performs an operation of supplying power for driving the motor using power supplied from a power supply unit. The power element may supply power for driving the motor th...
