A modular inverter including a capacitor unit including two or more capacitors arranged at a first side, a first capacitor busbar contacting a lower end of the capacitor unit and including a first capacitor connection portion including a first portion located on a second side of an upper end of the capacitor unit, a second capacitor busbar covering the upper end of the capacitor unit and including a second capacitor connection portion including a second portion extending outwardly to a third side of the upper end of the capacitor unit, a cooling unit disposed above the second capacitor busbar, and one or more power modules disposed above the cooling unit, the one or more power modules including a first power module busbar and a second power module busbar extending to the third side of the upper end of the capacitor unit and connected to the second capacitor connection portion.

Modular inverter and large-capacity inverter assemblies including the modular inverter

In the present invention, in order to reduce parasitic inductances of a gate line and a source line of a power module to reduce a current deviation (current balancing) which is a problem when the power module composed of a plurality of parallel chips is driven, in a power module including a plurality of power semiconductor chips connected to gate lines and source lines extending from gate pins and source pins in parallel by different distances, a current area of each of the gate lines and the source lines connected to chips other than a first chip closest to the gate pin and the source pin is formed larger than a current area of each of the gate line and the source line connected to the first chip.
