Meet Ingeteam: Pioneers in Sustainable Energy Solutions

Ingeteam is a global company with about 3,500 employees in 15 countries. Founded in the year 1972, it has many years of experience in providing innovative solutions to specific problems, to electrify society innovatively and sustainably through state-of-the-art technology specializing in the conversion of electrical energy. Ingeteam generated a turnover of 842 million euros in 2022. Around 40 million euros were invested in R&D.

The products of the company include chargers for electric vehicles, converters, alternators, and engines for various sectors such as marine, steel, mining, and water management.

Overcoming Extreme Conditions: Ingeteam’s Quest for High-Performance Capacitors

Focusing on innovation and performance in the renewable energy market requires components that can withstand extreme operational conditions. This includes elevated temperatures due to direct sunlight and confined spaces, high humidity, and salt spray from seawater. In addition, Ingeteam has been working with a new generation of semiconductors. Wide bandgap power semiconductors like silicon carbide (SiC) MOSFETs push the limits of performance and efficiency by switching much faster than silicon IGBTs. This fast switching poses extra stress on the surrounding components like the DC-link capacitor.

The key challenge lies in finding capacitors that can perform under the high-frequency demands of these converters while maintaining high current capability, low ESR (Equivalent Series Resistance), and low ESL (Equivalent Series Inductance), all within a compact size. A low ESR is important because it minimizes energy losses and improves performance in high-frequency high-power applications. Similarly, low ESL is crucial as it enables faster transient response and lower EMI. Specifically, when using fast-switching devices like SiC MOSFETs and the latest silicon IGBTs, the ESL must be extremely low to reduce voltage overshoots at turn-off. A low ESR also limits self-heating, thereby improving the thermal performance of the component. Together, low ESR and ESL enhance the overall stability and reliability of the converter.

With all these challenging demands, Ingeteam needed a solution that not only met their stringent technical specifications but also allowed standardization and modularization across their range of products.

• A photo-spintronic conversion element capable of responding at ultra-high speeds of 20 picoseconds using light with 800 nm wavelengths, 10X faster than conventional semiconductor-based photo detectors 

• Concepted and developed by TDK, the magnetic device can detect both near-infrared and visible light

• Successfully demonstrated operation in collaboration with Nihon University in Japan, known for fundamental physics research 

• It can be applied to photoelectronic conversion technology, which is expected to improve data processing speed and reduce power consumption, both critical for further AI evolution 

TDK Corporation (TSE:6762) announces that it has developed the world’s first* “Spin Photo Detector,” a photo-spintronic conversion element combining optical, electronic, and magnetic elements that can respond at an ultra-high speed of 20 picoseconds (20 × 10⁻¹² s) using light with a wavelength of 800 nm [1] – more than 10X faster than conventional semiconductor-based photo detectors. This new device is expected to be a key driver for implementing photoelectric conversion technology that boosts data transmission and data processing speed, particularly in AI applications, while simultaneously reducing power consumption. 

Transferring mass amounts of data at higher speeds and with lower power consumption is an inevitable need as AI evolves. To process data and make calculations, data is currently transferred between CPU/GPU chips as well as from and to memory by electrical signals. Therefore, there is an increasing need for optical communication and optical interconnects, which offer high speeds that do not decrease with interconnect distance. Photoelectronic conversion technology is also gaining global interest as a very compact fusion of both optical and electronic elements. 

To address these challenges, TDK adapted its magnetic tunnel junction (MTJ) technology, which is currently used in billions of HDD heads, for photonics. One of the major advantages of this technology is that it does not require crystal growth using a single crystal substrate, and the device can be formed regardless of the substrate material. Comparatively, conventional semiconductor-based photo detectors have physical limitations at shorter wavelengths. Because the Spin Photo Detector has a completely different operating principle and uses an electron heating phenomenon, it can operate at ultra-high speeds even when the wavelength is shortened [1]. In addition, the operating wavelength range is wide, and it has been confirmed that it can operate from visible light to near-infrared light. TDK has successfully demonstrated the Spin Photo Detector with Nihon University in Japan, a research pioneer for the measurement of ultrafast phenomena of magnetic material.  

Additionally, with the ability to detect visible light at high speeds, the spin photo detector will be useful in applications projected for future growth, such as devices for AR/VR smart glasses ([2], [3]) and high-speed image sensors. While conventional semiconductor photo-sensing devices have weak cosmic-ray resistance, MTJ elements are also known for their strong cosmic-ray resistance and are expected to be used as light-detecting elements in aerospace applications. In the future, based on these results, TDK will improve the perfection of the high-speed light detection element to further pursue its usefulness.

TDK Corporation (TSE: 6762) has expanded its CGA series for automotive multilayer ceramic capacitors (MLCCs) to 10 µF at 100 V in 3225 size (3.2 x 2.5 x 2.5 mm – L x W x H), with X7R characteristics (Class Ⅱ dielectric). This is the industry’s highest capacitance* for a 100-V rated product in 3225 size and this temperature characteristic. Mass production of the product series began in April 2025.

While power consumption has increased and high-current systems have become more widespread in recent years with the increasing sophistication of ECUs, there is also demand for lighter vehicles (with lighter wiring harnesses), and the use of 48 V battery systems is becoming increasingly widespread. With this, there has been an increasing demand for high-capacity 100-V products, such as smoothing and decoupling capacitors used in power lines. 

CGA series 100-V products achieve twice the capacity of conventional products of the same size thanks to optimized material selection and product design. This new product makes it possible to halve the number of MLCCs used and the mounting area, contributing to the reduction of component count and miniaturization of sets. TDK will further expand its lineup to meet the needs of customers.
