Abstract
Provided herein is a power converter component to power a drive unit of an electric vehicle drive system. The power converter component includes an inverter module formed having three half-bridge modules arranged in a triplet configuration for electric vehicle drive systems. Positive inputs, negative inputs, and output terminals of the different half-bridge inverter modules are aligned with each other. The inverter module includes a positive bus-bar coupled with the positive inputs and a negative bus-bar coupled with the negative inputs of the half-bridge inverter modules. The positive bus-bar is positioned adjacent to and parallel with the negative bus-bar. The inverter module can be coupled with a drive train unit of the electric vehicle and provide three phase voltages to the drive train unit. Each of the half bridge modules can generate a single phase voltage and three half-bridge modules arranged in a triplet configuration can provide three phase voltages.
