ROHM has developed four models as part of the TRCDRIVE pack™ series with 2-in-1 SiC molded modules (two of 750V-rated: BSTxxxD08P4A1x4, two of 1,200V-rated: BSTxxxD12P4A1x1) optimized for xEV (electric vehicles) traction inverters. TRCDRIVE pack™ supports up to 300kW and features high power density and a unique terminal configuration – help solving the key challenges of traction inverters in terms of miniaturization, higher efficiency, and fewer person-hours.
As the electrification of cars rapidly advances towards achieving a decarbonized society, the development of electric powertrain systems that are more efficient, compact, and lightweight is currently progressing. However, for SiC power devices that are attracting attention as key components, achieving low loss in a small size has been a difficult challenge. ROHM solves these issues inside powertrains with its TRCDRIVE pack™.
A trademark brand for ROHM SiC molded type modules developed specifically for traction inverter drive applications, TRCDRIVE pack™ reduces size by utilizing a unique structure that maximizes heat dissipation area. On top, ROHM’s 4th Generation SiC MOSFETs with low ON resistance are built in – resulting in an industry-leading power density 1.5 times higher than that of general SiC molded modules while greatly contributing to the miniaturization of inverters for xEVs.
The modules are also equipped with control signal terminals using press fit pins enabling easy connection by simply pushing the gate driver board from the top, reducing installation time considerably. In addition, low inductance (5.7nH) is achieved by maximizing the current path and utilizing a two-layer bus-bar structure for the main wiring, contributing to lower losses during switching.
TRCDRIVE pack™ is scheduled to be launched by March 2025 with a lineup of 12 models in different package sizes (Small / Large) and mounting patterns (TIM: heat dissipation sheet / Ag sinter). In addition, ROHM is developing a 6-in-1 product with built-in heat sink that is expected to facilitate rapid traction inverter design and model rollout tailored to a variety of design specifications.

As the deployment of Energy Storage Systems (ESS) accelerates, there is a critical need for compact and high-efficiency Power Conversion Systems (PCS) optimized for ESS applications. To address this requirement, Semikron Danfoss K.K. and Headspring Inc. have joined forces to develop advanced PCS solutions specifically for ESS, targeting mass production by 2026. This collaboration aims to enable more efficient and space-saving storage solutions.
Energy Storage Systems are essential components for renewable energy and power grids, ensuring resilience and stable supply. The global ESS market is projected to grow by 20%-30% annually, with expectations to exceed 400 GWh of storage systems worldwide by 2030. This exponential growth is driven by the increasing share of renewable energy in the grid, necessitating the accelerated deployment of ESS solutions for stable grid operation.
To address this rapidly growing market, Semikron Danfoss is developing a series of adaptable power solutions. Central to this initiative is the ANPC (Active Neutral Point Clamping) topology for ESS, which demonstrates a significant performance improvement by reducing power loss by over 50% compared to traditional NPC/MLI topologies. However, to fully harness the potential of ANPC technology, collaboration with Headspring is crucial. Headspring’s expertise in high-speed controller technology is vital for effectively controlling ANPC systems and ensuring optimal performance.
Semikron Danfoss brings extensive expertise and innovation in power electronics to the ESS market. Their ANPC technology in LF/HF configuration, featuring a hybrid circuit of silicon IGBTs and silicon carbide MOSFETs, significantly enhances efficiency and cost performance. The availability of ANPC power modules in PCB-mountable, industry-standard housings reduces both material and assembly costs, making them ideal for high-volume production.
The ANPC power modules provided by the SEMITOP E2 platform offer superior thermal performance, contributing to the downsizing and high-capacity PCS for ESS. Semikron Danfoss aims to set new benchmarks in ESS performance and value with their comprehensive design package that supports improvements in both hardware and software.
Headspring excels in developing high-speed real-time controllers essential for power electronics applications. Headspring’s controllers combine commercial microcontrollers with FPGA technology, providing flexible programming tailored to the specific demands of power electronics applications. Headspring has participated in the Strategic Innovation Promotion Program (SIP) “Energy Systems for an IoT Society by Japan’s Cabinet Office,” leading the development of ultra-high-speed controllers for power electronics. These controllers, integrating high-speed multi-core CPUs, high-performance FPGAs, and high-speed AD converters, achieve a feedback control performance of 50MHz, approximately 1000 times faster than conventional systems.
Semikron Danfoss and Headspring are collaborating to develop a compact, high-efficiency PCS tailored for large-scale, scalable ESS applications by integrating Semikron Danfoss’s ANPC technology-based power modules with Headspring’s advanced controller technology. Semikron Danfoss will offer the expertise for developing the power stack, which includes power modules, drive circuits, and coolers, while Headspring will be responsible for the controllers, peripheral circuits, software, and PCS integration.
This synergy aims to create an ESS-specific PCS with optimized cost, efficiency, and size. A primary goal is to enable containerized ESS solutions to increase storage capacity per 20-foot container from 3.3MWh to 5MWh. This will establish a roadmap setting hardware and software benchmarks for ESS performance, delivering superior ESS solutions that promote the advancement of renewable energy technologies.

Crystal IS, an Asahi Kasei company, announced production of 100 mm diameter single-crystal aluminum nitride (AlN) substrates with 99% usable area, based on current requirements for UVC LEDs. This improved quality is steadily approaching that of Crystal IS’ existing 2-inch substrates used in the production of its UVC LEDs. The ultra-wide bandgap and high thermal conductivity of AlN helps improve device reliability and performance in both UVC LEDs and other next generation RF and power devices.
“The improvement of our large diameter substrate quality over the last nine months showcases the expertise of our team in aluminum nitride innovation,” said Eoin Connolly, President and CEO of Crystal IS. “The inherent benefits of aluminum nitride are unlocking new applications in RF and power devices—we are excited to work with our partners to further develop this material to meet their needs.”
This achievement follows the company’s announcement of the first ever recorded 100 mm diameter in August 2023, which won an excellence award at Semiconductor of the Year in electronic materials for the Semiconductors Category. The Semiconductor of the Year Awards are organized by Electronic Device Industry News, an industry journal published in Tokyo by SangyoTimes Inc.
Crystal IS manufactures bulk aluminum nitride substrates at its headquarters in Green Island, New York and began selling 2-inch diameter substrates for research and development in RF and power devices in late 2023. This 100 mm diameter milestone accelerates the development of new applications on aluminum nitride substrates as it integrates into existing fabrication lines for power and RF devices using alternative materials. The company plans to offer 100 mm diameter substrates manufactured in its US facility to key partners this year as they expand their focus beyond UVC LEDs.
