In electric vehicles (xEVs), thermal management plays a crucial role for battery safety and longevity, inverter and motor monitoring, and comfort also. For this purpose, TDK offers a broad variety of innovative NTC and PTC based temperature sensors solutions, optimized by their design and specification for the respective applications. However, advanced Micronas Hall sensors and motor controllers also perform important tasks, for example in the high-precision control of valves.

Topologies with inverter circuits for power conversion have increasing importance in the automotive electronic applications. The selection of the right capacitor for the DC-link function is the key to achieve the best solution in terms of electrical function, mechanical and thermal requirements, as well as cost optimization.

TDK has the largest variety of technologies and product portfolio for all concerned inverter applications in order to serve his customers best. This application support gives a perfect overview to make the right decisions for the best solution.

Inverters are used in battery-electric or fuel cell vehicles. The semiconductors used in them generate electromagnetic interference through their switching processes when converting energy from direct current (DC) to alternating current (AC) and vice versa. 
With the CarXield TDK Corporation now presents the first standard EMC filter platform for automotive applications and thus a cost-effective, efficient solution to EMC problems. The CarXield is available in several variants and can be used at voltages of 500 V DC or 900 V DC with currents up to 400 A @85 °C. 
Thanks to its fully validated design, filters with or without busbar are always available. Further customization for your exact application can be made and developed on the fly.

CLARA is an intuitive search-oriented simulation tool for TDK and EPCOS film capacitors. It helps designers to find the most suitable product for their application conditions in just a few clicks. Within the design tool specifications of different products and the performance of the products under customer-specific application conditions can be simulated easily. Additionally, CLARA allows to include personal notes during a search and it is directly linked to the TDK Product Center for sample requests or product inquiries.

TDK’s High-Voltage Contactor (HVC) Series is designed to meet the demands of high-voltage and high-current DC applications, especially for the disconnection for high-voltage lithium ion batteries. The hermetically sealed and gas-filled design is based on more than 80 years of experience with gas tube technology. The HVC series can be used in a wide range of applications where fast and reliable disconnection of high DC voltages is required.

CeraLink is a family of very compact capacitors for stabilizing voltages in the DC link. They are therefore suitable for use as either snubber or DC link capacitors. These products are based on PLZT ceramics and are designed to provide engineers with compact components optimized for fast switching converters, converters with very tight space requirements and converters that need to withstand high operating temperatures.

The fields of application of dual inductors are diverse. They can be used as coupled inductors in various non-isolated DC/DC converter topologies or as transformers in flyback converters. A further application involves the use as common-mode inductors in power supply lines. TDK´s dual inductor series offer coupling factors up to 99%. The compact robust designs feature functional isolation voltages between the two windings up to 500 V.
