Asahi Kasei developing fast response current sensing tech

This technology is suitable for high frequency applications and will allow for smaller, more efficient electrical systems.

AKM will demonstrate the new technology for the first time from 9-11 May at PCIM Europe.

Utilising this technology substantially increases the switching frequency of power supply systems, such as AC-DC and DC-DC converters, contributing to the overall size reduction of electrical systems.

It is suitable for high frequency control in applications using silicon carbide (SiC) or gallium nitride (GaN) switching devices, as well as for the overcurrent protection of electrical systems.

AKM is aiming to utilise this technology in automotive applications, such as on-board chargers and DC-DC converters.

At PCIM, the company will showcase an AC servomotor control demonstrator utilizing a coreless current sensor IC with a sigma-delta digital output, as well as the CZ375x, a coreless current sensor IC of the Currentier product line with a high current capability up to 100 Ampere root mean square (Arms).
