AI Infrastructure and Smart Power Systems Create New Demand
The expansion of data centers is emerging as a significant market catalyst. MMR highlights growing deployment of power-management systems in data centers to improve speed and efficiency while reducing electricity consumption. Current sensors support backup-power systems such as inverters and UPS equipment, helping protect batteries during charging and improve their effectiveness. Government policies focused on monitoring data-center power usage are adding further momentum.
The renewable-energy transition provides another structural growth engine. Converters and inverters are essential for converting and managing electricity generated from renewable sources, creating opportunities for current-transducer manufacturers as renewable technologies expand globally. MMR also identifies the increasing deployment of 5G as an opportunity for closed-loop current sensors.

Closed-Loop Technology Moves Into the Spotlight
Closed-loop current transducers are expected to hold the largest technology share by 2034. Their higher performance, increased bandwidth, and ability to virtually eliminate eddy currents position them for demanding applications requiring accurate and responsive current measurement.
Key Market Segments
By Technology: Open Loop, Closed Loop
By Application: Motor Drive, Battery Management, UPS & SMPS, Converter & Inverter, Others
By End User: Industrial, Automotive, Renewable, Residential & Commercial, Others
The Converter & Inverter application is projected to grow rapidly during 2026–2034. In photovoltaic inverters, current transducers support reaction control and precision of current-output waveforms, while fast-response closed-loop technologies strengthen control performance.
The renewable end-user segment is also expected to grow rapidly as the global energy system shifts toward renewable power generation. This creates opportunities across solar, power conversion, energy storage, and smart-grid applications.
Sensor Innovation Raises the Technology Benchmark
Recent product developments demonstrate how current sensing is moving toward smaller footprints, higher bandwidth, lower losses, and greater precision.
In February 2026, Allegro MicroSystems launched the ACS37017 Hall-effect current sensor, expanding its high-performance current-sensing portfolio for high-voltage power-conversion systems. MMR reports a typical lifetime and temperature sensitivity error of 0.55%, with applications including AI data centers and electric vehicles.
In January 2026, Allegro introduced the ACS37200 galvanically isolated current sensor for high-current industrial and automotive environments. Its integrated 50 µΩ conductor is reported to reduce power losses by up to 90% and sensor footprint by up to 95% compared with traditional solutions.
In October 2025, Allegro launched the ACS37100, a production-ready high-speed magnetic current sensor using Tunnel Magnetoresistance technology, offering 10 MHz bandwidth for fast-switching GaN and SiC power architectures.
Meanwhile, LEM expanded its IN Series in May 2025 with two closed-loop current transducers using fluxgate and digital FPGA technology, achieving bandwidth up to 2.5 MHz and delay times below 1 nanosecond.
