Infineon Unveils Integrated OBC Solution: Single MCU Controls Bidirectional OBC, SiC Devices Drive 800V Platform Upgrade - finance.biggo.com

As the electric vehicle (EV) industry rapidly evolves toward higher voltage and integrated systems, the on-board charger (OBC), a core power conversion unit, is undergoing a significant technological ... Read original →

Infineon’s new integrated OBC solution marks a pivotal shift in EV power conversion toward centralized control and 800V platforms. By integrating the AURIX TC4x microcontroller with CoolSiC devices, the company enables bidirectional CLLC topologies, enhancing efficiency and paving the way for future all-in-one power systems. This advancement pressures upstream semiconductor suppliers to accelerate innovation while forcing downstream OEMs to restructure their supply chains. From a compliance standpoint, global decarbonization policies and export controls on critical materials will intensify supply chain risks, particularly affecting suppliers in Taiwan, China and Hong Kong, China. Competitors like STMicroelectronics and TI may respond with accelerated product launches to capture market share. Over the next 12–24 months, the adoption of 800V platforms will accelerate, driving further consolidation in power device technologies toward SiC/GaN, pushing the industry into a new phase of high-tech competition.
