TDK Corporation Exhibits EV Power Solutions in Detroit

TDK-Lambda introduced advanced programmable DC power supply architectures through its GENESYS+ series, incorporating optional EtherNet/IP and PROFINET communication protocols for integration into automated manufacturing environments. The exhibits included GENESYS AG Power Booster Modules configured to deliver ratings up to 45 kVA to support high-power component testing and validation workflows.

High-Voltage Capacitance and Dielectric Technologies
The product presentation featured the upgraded 1,250 V CA MEGACAP series, incorporating a 99 nF variant utilizing Class 1 dielectric formulations for high-voltage power conversion stages. Automotive-grade film, hybrid polymer, and aluminum electrolytic capacitors were also demonstrated, highlighting surface-mount device hybrid polymer units with low equivalent series resistance and high ripple-current handling. Furthermore, AEC-Q200-qualified modular xEV film capacitors were showcased for direct current link inverter applications.

Power Distribution and Magnetic Components
The technical showcase detailed high-voltage contactors engineered for circuit isolation and protection within vehicle power distribution architectures. Magnetic component highlights included high-power transformers and inductors intended for Power over Coax networks, onboard charging hardware, and high-voltage inverters. Additionally, the AMT series of pulse transformers and surface-mount device insulated gate bipolar transistor and field-effect transistor gate-drive transformers were presented to minimize footprint dimensions in 500 V automotive battery systems.

Additional Context:
This section details technical specifications and competitive benchmarking not included in the original product announcement

The integration of EtherNet/IP and PROFINET standards into programmable DC power supplies aligns with industry shifts toward standardized industrial automation protocols (IEC 61158 and IEC 61784), reducing integration latency compared to legacy analog or proprietary serial control interfaces. In high-voltage DC-link applications, Class 1 dielectric ceramic capacitors provide superior capacitance stability across wide thermal variations compared to Class 2 alternatives, mitigating capacitance drop under DC bias conditions. Benchmarked against conventional toroidal wound components, planar and compact SMD gate-drive transformers reduce parasitic leakage inductance and volumetric profile, which is critical for high-frequency switching operations in silicon carbide and gallium nitride inverter topologies.
