Developers of automotive traction inverters are increasingly using three-phase power modules such as Infineon’s Hybridpack Drive. These modules are adopting SiC MOSFETtechnology, letting vehicles use 800V battery systems that offer faster charging and longer driving range.
LEM’s new HAH3DR S07/SP42 compact three-phase current sensor is designed to fit these 800V modules. Calibrated over temperature and stable over the unit’s lifetime, they enable quick time-to-market with little R&D effort. This suits companies developing small passenger vehicle platforms, trucks and buses, while restrained by limited R&D resources.
The sensor offers a wide selection of current measuring ranges from 700A to 1,200A. Compared to existing units in the HAH3DR family, the package isolation characteristics have been upgraded to cope with the challenge of 800V power modules.
The product offers a unique enlarged aperture to accommodate busbars up to 1.5mm thick, making it compatible with the newest generation of power modules.
