Abstract

The present invention relates to a power supply module and an inverter by using the same. The inverter includes: an upper module having three switching elements, among switching elements defining three poles of a three-phase inverter, which are connected to a positive electrode on a first substrate; and a lower module having three switching elements, among the switching elements defining the threepoles of the three-phase inverter, connected to a negative electrode on a second substrate. The upper module and the lower module are configured to be stacked on each other, and a positive terminal of the upper module and a negative terminal of the lower module are stacked so as to be opposite each other with an insulator placed therebetween.

Description

technical field [0001] The present disclosure relates to a power module configured to include a switching element and an inverter configured to drive a motor using the power module. Background technique [0002] In a hybrid or electric vehicle, an inverter is used to drive the electric motor. A plurality of switching elements, which are power semiconductors, are used in an inverter in order to accurately control the supply of three-phase alternating current to a motor. [0003] Inverters for controlling three-phase current typically require six switching elements, where two switching elements performing complementary switching are connected in series to form a single pole or leg, and three such poles are connected in parallel to the power supply , thus forming an inverter. [0004] In the related art, a power module has one switching element composed together with other necessary components such as diodes on one substrate, so that one inverter is configured by combining si...
