Abstract

A power module for an inverter which includes a base which has a plurality of slots are formed thereto, a plurality of building blocks inserted into the slots and power cables interconnecting the building blocks. Further, each of these building blocks is provided with a power element which corresponds to one phase. Thus, each building block in the power module may be replaced individually without having to replace the entire power module in case of a failure in a single power element of the power module.

Claims

1. A power module for an inverter comprising:

a base of which a plurality of slots are formed thereto;

a plurality of separate building blocks configured to be inserted into the slots of the base; and

power cables interconnecting the building blocks, wherein each building block is provided with a power element corresponding one phase.

2. The power module of claim 1, wherein a connecting aperture is formed to the building block for connecting to the base.

3. The power module of claim 1, wherein the plurality of building blocks comprise a U phase block, a V phase block and a W phase block.

4. The power module of claim 3, wherein the plurality of building blocks further comprise a building block having a DC booster.

5. The power module of claim 1, wherein a cooling line is formed in the base.
