AKM Successfully Demonstrates eFuse Proof of Concept for High Voltage Automotive Uses
Asahi Kasei Microdevices and Silicon Austria Labs Collaborate on Groundbreaking eFuse Technology for High-Voltage Applications
BonChip Electronics, a trusted distributor of Asahi Kasei Microdevices (AKM) products, is excited to announce the successful joint development of eFuse technology with Silicon Austria Labs (SAL). This innovative solution addresses critical needs in high-voltage applications like electric vehicles (EVs).
Enhanced Safety and Efficiency for Next-Generation Power Systems
The growing adoption of silicon carbide (SiC) and gallium nitride (GaN)-based power devices in EVs and other high-voltage applications necessitates a paradigm shift in system protection. Traditional mechanical fuses, commonly used with silicon (Si) power converters, have limitations in response speed and overall system efficiency.
Introducing the eFuse Solution
AKM's CZ39 coreless current sensor, boasting a remarkable 100 ns response time and exceptional accuracy, forms the core of the eFuse system. Developed collaboratively with SAL, this solution offers:
- Precise Overcurrent Detection: The eFuse system accurately detects overcurrents, enabling immediate system shutdown and preventing damage to SiC- and GaN-based power devices.
- Enhanced Safety: This rapid response time translates to significantly improved safety in high-voltage systems, especially in EVs.
- Reduced System Complexity: The integrated current sensor in the eFuse eliminates the need for additional components, streamlining system design and reducing part count.
- Cost-Effective Maintenance: Replacing mechanical fuses with the eFuse technology minimizes maintenance costs associated with manual fuse replacements.
Industry Leaders Combine Expertise
"This joint technology validation marks a significant advancement in eFuse technology," said Toshinori Takatsuka, General Manager of AKM's current sensor business. "We are proud to have collaborated with SAL's research prowess to achieve this innovative solution. The eFuse technology holds immense potential to contribute to the development of smaller and lighter EV onboard chargers (OBCs)."
Looking Ahead: Positive Market Impact and Continued Collaboration
Thomas Langbauer, Team Lead within the Power Electronics Division at SAL, emphasizes the role of AKM's technology: "By leveraging AKM's cutting-edge current sensing technology, we are able to significantly improve the reaction time of eFuses and provide superior protection for wide-bandgap power converters."
AKM will showcase the results of this joint research at PCIM Europe 2024 (Nuremberg, Germany) in June. Both companies are actively exploring further collaboration and anticipate a positive market impact for the eFuse technology.
