Smaller, Lighter DCDC Converters Seen Contributing to Spread of Evs, Smart Grids.
Osaka (Japan) - Diamond Electric Mfg. Co., Ltd. developed a buisness card-sized, thin isolated bidirectional DCDC converter (IBDC) in december 2017. The technolgoy can substantially downsize and reduce the weight of DCDC converters, which are essential for recharging batteries, and is expected to contribute to spreading electric vehicles (EVs) and smart grids.
In recent years, requirements of large-capacity batteries for Evs and smart grids are causing rechargeable batteries to have higher voltage. Therfore, demands are growing for higher-level isolation of DCDC converters to ensure safety and meet safety standards.
In response, Diamond Electric has developed the new IBDC by fully utilizing its unique controlling technology (for which patent is pending). The IBDC combines both charger and discharger circuits.
By adopting high-frequency switching technology (up to 2MHz), Diamond Electric has developed an ultra-compact IBDC (03.5 mm x 60 mm x 10.5 mm excluding control circuit and heatsink).
Furthermore, the use of gallium nitride (GaN) power semiconductor enabled the achievement of high conversion efficiency (up to 95%) despite teh high-frequency switching. By utilizing these technologies, the company expects to downsize the final product to 25% of other existing models.
Listed on the Tokyo Stock Exchange (6895), the company is a leading manufacturer of ignition coils for automobiles, operating for 80 years. It also designs and manufactures a variety of DCDC converters, such as power conditioners and onboard DC/DC converters.
