High energy, reliable and volumetric efficient inverters are essential to reducing emissions of vehicles based on 48 V technology. DC-link capacitors can significantly contribute to this target by reducing parasitic losses and increasing thermal efficiency. High inverter powers can be theoretically achieved with multiple capacitor connections. However, a high number of parallel-connected parts also increase the complexity of the system stability. In the field of Aluminum Electrolytic Capacitors, the Hybrid Polymer technology offers higher ripple current densities by a factor of, e.g., 5x compared to standard Liquid Electrolyte technology. By applying the Hybrid Polymer technology to the large axial capacitor can sizes, with solid mechanical construction and special thermal dissipation feature, a compact DC-link solution with a reduced amount of capacitor and minimized thermal escalation risk through stable and efficient thermal design can be achieved.

Service robots play an increasingly vital role in society, from transportation and warehouse logistics to home entertainment and security. Regardless of their application, they need to sense changes in their surroundings in real-time to ensure safety while providing a positive user experience. To illustrate how various sensor technologies from TDK’s SmartSensor family can be applied in service robots, this article focuses on a robotic vacuum cleaner (RVC).
Early versions of robotic vacuums had very little intelligence, randomly bumping their way around the home and sometimes missing areas as they did not know where they had been. Often, they would unwittingly become trapped or run out of charge mid-sweep. And, as their dust box is comparatively small to a regular vacuum cleaner, if full, they could be sweeping but not collecting anything up. Over the years, with the innovative use of sensors and motor controllers, vacuum cleaning robots have become much smarter, overcoming these issues.

The demand for higher data rates at the edge has increased significantly. The adoption of cameras and video system has increased driven by the reduced footstep of these systems and their usage for safety, security and quality applications. Other systems like high-speed data logging devices, embedded web servers and monitoring systems require a timely data transmission.
In addition, the number of nodes in networks are constantly increasing therefore the desire to use an existing ecosystem is strong. Ethernet protocol and security layers as well as well-known installation, maintenance and management processes result in a lower Total Cost of Ownership (TCO) and a better Return on Investment (ROI) in the Network.
Industrial applications focus on a network speed of 10 Mbps as this should address the data rate and reach for most of the existing fieldbus applications. TDK offers an extensive lineup of various inductors for use in 10Base-T1L applications including common-mode chokes (CMCs), isolation inductors (Isolated Coupled Inductors) and differential mode inductors (DMIs).
