ROHM showcasing latest power electronics at APEC 2025
In booth 1223 at IEEE Applied Power Electronics Conference & Exposition (APEC 2025) in Atlanta, GA, USA (16–20 March), ROHM Semiconductor USA LLC is presenting its latest power electronics technologies designed to improve power density and efficiency in automotive and industrial equipment applications while achieving smaller form factors and greater reliability.
The latest models offer insights for application design and innovation, supporting customers in addressing social and environmental challenges.
Automotive applications
- SiC molded power modules for electric vehicles (EVs):
ROHM is showcasing TRCDRIVE pack, a 2-in-1 silicon carbide (SiC) molded module that improves the efficiency of traction inverters. A variant designed for auxiliary systems such as on-board chargers (OBCs) is also on display.
- Scalable PMIC demonstration:
ROHM is exhibiting the REF66004 reference design featuring the scalable BD96801Q12 power management integrated circuit (PMIC) suitable for automotive system on chip (SoC). 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 is presenting 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 suitable for electric drills, screwdrivers, and industrial cooling fans.
- 3kW totem pole PFC with 650V GaN HEMT:
ROHM is exhibiting a 3kW output totem-pole-type PFC (power factor correction) circuit incorporating 650V GaN HEMTs from the EcoGaN series. This high-efficiency solution is optimized for power supplies in communication base stations, servers, and energy storage systems (ESS).
Design-ins
- Murata Power Solutions: AI server power supplies:
ROHM’s EcoGaN series of 650V GaN HEMTs in the TOLL package has been integrated into 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 is exhibiting an inverter unit utilizing the TRCDRIVE pack featuring a 2-in-1 SiC molded module.
