The invention discloses a power module provided with partition electrodes, which comprises a plurality of insulating substrates arranged in a row. There is a first electrode lead-out part on the upper right of the rightmost lower half-bridge insulating substrate. The first electrode lead-out part is bent to the left and connected to the lower half-bridge insulating substrate through the first electrode main part. The right side of the first electrode lead-out part is provided with The second electrode lead-out part, the second electrode lead-out part is bent to the right and connected to the lower half-bridge insulating substrate through the second electrode main body; the upper right of the leftmost upper half-bridge insulating substrate is provided with a third electrode lead-out part, the third electrode The lead-out part is bent to the left and connected to the upper half-bridge insulation substrate through the third electrode main part, and the fourth electrode lead-out part is arranged on the right side of the third electrode lead-out part, and the fourth electrode lead-out part is bent to the right and connected to the fourth electrode main body. The upper half-bridge insulating substrate; and the first electrode main body, the second electrode main body, the third electrode main body and the fourth electrode main body are not in contact with each other.
Description
technical field [0001] The invention relates to the field of power electronics, in particular to a power module provided with isolated electrodes. Background technique [0002] The power module is a power switch module packaged by power electronic devices such as metal oxide semiconductors (power MOS tubes), insulated gate field effect transistors (IGBTs), and fast recovery diodes (FRDs) according to certain functions. Power conversion in various occasions such as automobiles, photovoltaic power generation, wind power generation, and industrial frequency conversion. [0003] In the three-level power module in the prior art, the intermediate electrodes that supply power to the lower half-bridge insulating substrate and the upper half-bridge insulating substrate are often integrated, which is inconvenient to manufacture and install. Contents of the invention [0004] Object of the invention: The object of the invention is to provide a power module with partition electrodes ...
