Circuit arrangement for an n-phase electric machine, electric machine for a vehicle, vehicle and method for operating an n-phase electric machine

摘要

The invention relates to a circuit arrangement (2) for an n-phase electric machine (1), comprising a first current sensor (8a) to be associated with a first phase conductor (6a) for detecting its current intensity, and n-1 further current sensors (8b, 8c), which are each assigned to one of the remaining phase conductors (6b, 6c) for detecting its current intensity and which each have a higher measuring accuracy than the first current sensor (8a).
