Output Voltage Synthesis of a Modular Battery System based on a Cascaded H-Bridge Multilevel Inverter Topology for Vehicle Propulsion: Multilevel Pulse Width Modulation vs. Fundamental Selective Harmonic Elimination
2020 IEEE Transportation Electrification Conference & Expo (ITEC)
Lately, the research interest for modular battery systems has increased due to the possibility of a better utilization of individual battery packs/cells and the steadily reducing costs of low voltage power electronics. This paper deals with the output voltage synthesis of a modular battery system based on a seven level Cascaded H-bridge (CHB) inverter topology used in a small passenger vehicle. Two methods are considered, Multilevel Pulse Width Modulation (MPWM) and Fundamental Selectivedoi:10.1109/itec48692.2020.9161658 fatcat:fezwbizxn5fl5bknbhuqdq5x7i
