Santa Clara, California and Kyoto, Japan, December 4, 2024 (GLOBE NEWSWIRE) — ROHM Semiconductor today announced the adoption of its EcoSiC™ products, including SiC MOSFETs and SiC Schottky barrier diodes (SBDs), in the HFA/HCA series of 3.5 kW output AC-DC power units for three-phase applications from COSEL, a leading power supply manufacturer. in Japan. The integration of ROHM’s SiC MOSFETs and SiC SBDs into the forced-air-cooled HFA series and the conduction-cooled HCA series achieves an efficiency of up to 94%. The HCA series has been mass produced since 2023, while the HFA series began mass production in 2024.
Many industrial applications that handle high power in the industrial sector, including MRI machines and CO2 Lasers require three-phase power supplies that are different from the single-phase power supplies used in households. COSEL’s AC-DC power supplies – equipped with ROHM’s EcoSiC technology that excels in high temperature, high frequency and high voltage environments – are compatible with three-phase power supplies from 200 VAC to 480 VAC, helping to improve the power efficiency across a wide range of industrial equipment worldwide.
Jun Uchida, General Manager, New Product Development Department 2, COSEL Co., Ltd.
“The HFA/HCA series achieves high efficiency, despite a high output power of 3.5 kW, by incorporating ROHM’s low-loss SiC power devices. Operating at high input voltages typically poses a challenge in reducing losses in high-voltage power devices, but the use of SiC power devices results in significantly lower losses compared to conventional solutions , resulting in power supplies that maintain high efficiency and power density, even under demanding conditions. power conditions.
Akihiro Hikasa, Group General Manager, Electrical Appliances Business Unit, SiC Business Section, ROHM Co., Ltd.
“We are pleased to support COSEL, an industry leader in electrical power systems, by providing SiC power devices. A leading company in the field of SiC power devices, ROHM also offers complete power solutions combining peripheral components. Additionally, by addressing customer issues, we also improve device performance by integrating the acquired information into our products. In the future, we will continue to collaborate with COSEL to contribute to a sustainable society by improving the efficiency of industrial equipment that processes large amounts of energy.
HFA/HCA Series 3.5 kW Output AC-DC Power Units for 3-Phase Power Supplies
The HFA/HCA series are 3.5 kW power supplies with a wide input range (200 VAC to 480 VAC) that meets global power requirements. This allows them to be used anywhere in the world without the need to change each region’s power supply, helping to standardize application designs. The forced air-cooled HFA series and conduction-cooled HCA series models (selectable based on operating environment) are available in 48V and 65V output voltage variants that can be used as sources power supply for a variety of high-power applications, such as lasers. generation and MRI.
