Düsseldorf and Tokyo – Asahi Kasei Microdevices (AKM) is developing a new ultra-fast response current sensing technology. This technology is ideal 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 2023 at PCIM Europe.
To further optimize efficiency and packaging size of high frequency applications, Asahi Kasei Microdevices is developing a new current sensing technology featuring an ultra-fast response time. Utilizing 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 ideal 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. In the future, Asahi Kasei Microdevices is aiming to utilize this technology in automotive applications, such as on-board chargers and DC-DC converters.
Asahi Kasei Microdevices will showcase the new technology for the first time in a demonstration showing the ultra-fast measurement of a triangular current wave at PCIM Europe, the leading international exhibition and conference for Power Electronics, Intelligent Motion, Renewable Energy and Energy Management, from 9-11 May 2023 in Nuremberg, Germany. In addition, 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).
