工業用AC-DC轉換器

除了主電源電路外,工業用AC-DC轉換器還需要具備為各種控制系統提供電源電壓的輔助電源電路,電路結構(拓撲)更是多樣化。羅姆針對不同的拓撲結構工業電源設備,備有半導體元件、IC和模組等各種產品系列,可以為一次側和二次側、絕緣和非絕緣、Discrete結構和內置IC結構等,提供實現相對應優異性能的解決方案。

Topology Selection

When designing an electronic circuit, especially power system circuits, it is necessary to select a circuit configuration (topology) that meets the required specifications because input voltage, output voltage, power, isolation, etc. vary depending on the application. The selection of the most suitable components also differs depending on the topology. If the wrong components are selected, the required specifications cannot be met and the circuit design must be redone. The topology selection page provided by ROHM guides you through the selection of the best device for different topologies.

Flexible lines

ROHM Apollo’s Hirokawa Factory in Fukuoka Prefecture began operating a new semiconductor back-end process line. Sample production for sales expansion started April 2021. The following year, in 2022, we began mass producing discrete products. The clean room, which embodies the concept of an ‘unmanned high-mix production line’ features a compact design using three sets of equipment neatly arranged in a U-shape with AGVs (Automated Guided Vehicles) running between them. Technicians monitor the status of all lines via monitors in an adjacent control room.
