With the development of power semiconductor technology, the voltage rating of IGBT has been developed from 1200V, 1700V to 3300V, 4500V or even 6500V. In high-voltage applications, such as high-voltage inverters, high-voltage reactive power compensation, and rail transit, it was achieved in the past. The method of high voltage resistance is that a plurality of 1700V IGBTs are connected in series, but the reliability of the discrete modules is reduced by several times, and problems such as uneven voltage division and excessive volume are easily caused. At present, high-voltage IGBT manufacturing technology is relatively mature in the world, but high-end technology is still monopolized by foreign countries, the product cost-effectiveness is not high, domestic applications are still in the initial stage.
As the first domestic company engaged in the development of IGBT driving technology, Beijing Lamyuan Electronics Co., Ltd. has independently invented patented invention technology that began in 1995 and currently enjoys a good reputation and influence in China. Falling wood source electron enters the high voltage IGBT this frontier area since 2007, increase R&D investment constantly, presently has rolled out a series of high voltage IGBT driver products, including DF10x series (fibre isolation, used for 6500V, 4500V, 3300V), DE106Dx series (transformer Isolated, used for 4500V, 3300V, 2500V) and other models, while developing a supporting high-isolation module power supply, including PD220 (isolation voltage ≥ 15KV), PD106 (isolation voltage ≥ 7KV) and other products.
The DF10x series includes DF101 (Dual Drive), DF102 (Plug and Play), and DF103 (Simplified Powerless), all using fiber optics for signal isolation transmission and can be applied to the highest level 6500V IGBT modules, including DF102 screws Directly fixed installation supports various types of IGBT modules such as Infineon, ABB, Mitsubishi and other models directly plug and play, increasing reliability and reducing debugging difficulty.
The DE106Dx series includes DE106D1 and DE106D2, which are a unit and a two-cell output. The inside of the DE106D1 and DE106D2 are driven by the driver chip KE106. The transformer is used for signal isolation and transmission, and the output current is up to 30A. The PD106 with a 7KV high breakdown voltage drive power supply is suitable for driving a full range of 4500V. , 3300V or 2500V IGBT modules. Among them, the DE106D1 is a screw-in, plug-and-play design that can support the direct mounting of multiple brands of different models of IGBT modules.
Falling wood source electronics focuses on the IGBT drive circuit, focusing on product quality, all core components tested and screened one by one to ensure product reliability and consistency. IGBT drivers are used as device-level products. Few manufacturers, such as Lumber Source Electronics, are aging their products one by one. It also makes the reliability of Lianyuan Electronics' industry leading in the industry.
The IGBT driver researched and developed by Leverwood Electronics has its own short-circuit overcurrent protection function, and adopts an overcurrent soft turn-off technology that is superior to other products of the industry, which can effectively reduce the risk of IGBT damage. At the same time, customers can set protection threshold according to their own requirements. Blind zone, soft off time and other parameters, so that the applicability of the product has been greatly improved. In addition to providing general-purpose products, Limuyuan Electronics can quickly respond to customers' customized needs and provide a complete set of solutions to maximize the individual needs of different customers.
