The Growing Ecosystem for eGaN FET Power Conversion

Figure 1: Building blocks of a typical synchronous GaN buck converter.

In recent years, GaN-based power conversion has increased in popularity due to the inherent benefits of eGaN FETs over conventional Si transistors. Migrating a converter design from Si to GaN offers many system-level improvements, which require consideration of all the components in that system. This trend has su

Powering the Robotic Future

Figure 1: The motion control unit is wired to each actuator separately; fitted effectors require their own, separate wiring harness.

The world of manufacturing is changing, driven by various Industry 4.0 initiatives. Amongst these solutions, closely coupled, internetworked robotic solutions have to be highlighted. Closely coupled in this regard doesn’t only mean the connection to the Internet or the Internet-of-Things (IoT). The flexible networking of previously sequential, belt-supported pr
