Mini Power Module Integrates Coreless Current Sensing
Asahi Kasei Microdevices (AKM) and Silicon Austria Labs (SAL) have completed a proof of concept for integrating a high-resolution, coreless current sensor directly into a power module, streamlining inverter design for electric vehicles (EVs).
Built on a standard PCB using off-the-shelf components, it supports more accurate motor control and higher efficiency in variable load conditions. The new architecture was developed to help bring higher energy efficiency and enable compact, lightweight design for ultra-high-current applications using next-generation silicon-carbide (SiC) power devices.
The demonstrator module leverages AKM’s new EZ232L linear Hall IC and SiC power devices to deliver precise current sensing across a wide dynamic range without a magnetic core. Integrating these capabilities improves thermal performance, shrinks the footprint, and simplifies packaging for EV traction inverters, where space and weight are at a premium.
