Automotive applications
- Silicon carbide (SiC) molded Ppower modules for electric vehicles (EVs)
ROHM will showcase TRCDRIVE pack, a 2-in-1 SiC molded module that improves the efficiency of traction inverters. A variant designed for auxiliary systems such as on-board chargers (OBCs) will also be on display.
- Scalable PMIC demonstration
ROHM will exhibit the REF66004 reference design featuring the scalable BD96801Q12 PMIC ideal for automotive systems-on-chip (SoCs). This PMIC, which has been adopted in multiple power reference designs for next-generation cockpit SoCs, is scheduled to be installed in vehicles from leading European automakers.
Industrial equipment
- New three-phase motor driver for medium-voltage applications
ROHM will present a newly developed three-phase motor driver that leverages proprietary control technology to significantly reduce motor power consumption by minimizing switching losses. The compact design also contributes to smaller application size, making it ideal for electric drills, screwdrivers and industrial cooling fans.
- 3 kW totem pole PFC with 650V GaN HEMT
ROHM will exhibit a 3 kW output totem pole type PFC (Power Factor Correction) circuit incorporating 650 V GaN HEMTs from the EcoGaN series. This high efficiency solution is optimized for power supplies in communication base stations, servers and energy storage system (ESS).
Design-in success stories
- Murata power solutions: AI server power supplies
ROHM’s EcoGaN series of 650 V gallium nitride (GaN) HEMTs in the TOLL package has been integrated into artificial intelligence (AI) server power supply units from Murata Power Solutions. Adopting ROHM’s GaN HEMTs, which combine low loss operation with high-speed switching performance, allows these power supply units to achieve greater efficiency and miniaturization.
- Valeo’s inverter for EVs and PHEVs
Valeo and ROHM have been collaborating since 2022, initially focusing on technical exchanges to enhance the performance and efficiency of motor inverters, a critical component in EV and PHEV propulsion systems. ROHM will exhibit an inverter unit utilizing the TRCDRIVE pack featuring a 2-in-1 SiC Molded Module.
