Analysis of the THD and Common-Mode Voltage of the Three-Phase Boost-Buck EV Traction Inverter
A three-phase boost-buck inverter (BBI) comprised of three identical boost-buck DC/DC converter modules is presented for an EV traction inverter application. It allows the step-up and/or step-down of the battery pack voltage according to the operating condition of the traction motor so that the over...

| description | A three-phase boost-buck inverter (BBI) comprised of three identical boost-buck DC/DC converter modules is presented for an EV traction inverter application. It allows the step-up and/or step-down of the battery pack voltage according to the operating condition of the traction motor so that the overall performance can be optimized, which is essential for EVs with relatively low and varying battery voltages such as a hybrid EV or fuel-cell EV. It also features low switching losses, low harmonic distortion in the output current, and reduced common-mode voltage and/or current. A detailed analysis and performance evaluation of the BBI compared to the conventional technology demonstrate its feasibility in EV traction applications. The functionality and performance of the boost-buck inverter are verified with simulation and experimental results. |
