LEM has launched a new compact current sensor designed for 800V three-phase power modules.
Developers of automotive traction inverters are increasingly using three-phase power modules such as the popular and widely proven Hybridpack Drive from Infineon. These modules are now adopting the more efficient SiC MOSFET technology, allowing vehicles to use 800V battery systems that offer faster charging and longer driving range.
The new three-phase sensor from LEM has been designed to fit these 800V power modules. Fully calibrated over temperature and stable over the unit’s lifetime, it is ideal for companies developing small passenger vehicle platforms, trucks and buses while restrained by limited R&D resources.
It offers a wide selection of current measuring ranges from 700A to 1200A, and the package isolation characteristics have been upgraded to cope with the challenge of 800V power modules.
The sensor features an enlarged aperture that can accommodate busbars up to 1.5mm thick, making it compatible with newest generation of power modules. It is also compatible with power modules from various other suppliers, such as the Acepak Drive from ST Microelectronics, the SSDC from ON Semi, and others such as Starpower and CRRC.
