Diamond Electric Mfg. Co. Ltd. developed a business card-sized, thin isolated bidirectional DCDC converter (IBDC) in December 2017. The technology can substantially downsize and reduce the weight of DCDC converters, which are essential for rechargeable 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. Therefore, demands are growing for higher-level isolation of DCDC converters to ensure safety and meet safety standards. In response, the company has developed the new IBDC by fully utilizing its unique controlling technology (for which a 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 (93.5 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 the high-frequency switching. By utilizing these technologies, the company expects to downsize the final product to 25% of other existing models.
