Busbars are critical components that connect high-current and high-voltage subcomponents in high-power converters. This paper reviews the latest busbar design methodologies and offers design recommendations for both laminated and PCB-based busbars. In Proceedings of the 2023 IEEE Energy Conversion Congress and Exposition (ECCE), Nashville, TN, USA, 29 October–2 November 2023. Low Voltage Busbars: Refer to busbars with a rated voltage below 1kV, commonly. Distinguishing between high and low voltage busbars involves evaluating key factors such as electrical parameters, material selection, design standards, and real-world performance.
