"Electronic systems for smart power control are being increasingly installed in modern electrically-propelled vehicles, motors, and actuators for precise: a) position and motion adjustment, b) force and torque regulation, c) power efficiency optimization, and d) energy saving. The functionality of such controllers relies primarily on electric current sensors capable of monitoring precisely pulsed currents varying from DC up to frequencies as high as 100kHz and of reading current alteration rates as high as 10GA/sec. This requirement sets the sensor bandwidth specification to at least 1MHz for 5kA maximum current amplitude and resolution of 0.02% that is 1A. Additionally, modern power control applications require sending of current in multiple conductors positioned densely among each other. The aforementioned restriction poses limitations concerning sensor dimensions and cost as well as positioning distance between sensor and current conductors. Temperature stability is another important parameter that severely affects the performance of current sensors, especially in the case of industrial applications, where they are subjected to large temperature variations. The IHACS project aims at the development of a new family of very compact, galvanically isolated, open-loop, wide-band, self-calibrating current sensors. The sensors are based on sophisticated multi-axes CMOS HALL magnetometers with no ferromagnetic parts that employ a new, elaborate technique for sensitivity stabilization against temperature effects."
