Tokyo Electron announce newly developed IGBT gate driver
Tokyo Electron Device Limited (TED) has announced the launch of the newly developed IGBT (Insulated Gate Bipolar Transistor) gate driver TD-BD-IGFB05K with an on-board optical fibre interface that enables control of 1700V/1200A class IGBTs on a single board.
As plants for solar power generation, wind power generation and industrial-use inverters grow in size, systems for controlling high-voltage and high-current loads are becoming more complex. However, the reliability of such systems that use cables to connect with control boards cannot always be assured because of "noise," the effects of lightning, etc.
The TD-BD-IGFB05K, sold by TED under the "inrevium" brand, is a general purpose IGBT gate driver that enables simultaneous control of two 1700V/1200A class IGBTs. It has been developed by adding an optical fibre interface to TED's conventional IGBT gate driver TD-BD-IGGD05K. The TD-BD-IGFB05K is connected to a control board with an optical fibre, and directly connected with an IGBT module, so the risk of being impacted by "noise" or lightning is reduced, improving the security and reliability of the system.
When adopting a new IGBT, the major obstacles in the gate driver are the existence of an analogue control system for high voltage and high currents with a plus and minus power supply, and the insulation of the system for such high voltage and high currents. TED solves these problems with its line up of IGBT gate drivers. Each TED IGBT gate driver has a simple one-board configuration and enables easy IGBT control, allowing the user to concentrate on designing the main functions of the system.
Alongside the TD-BD-IGFB05K, TED has released the TD-BD-IGCC05K, which is a downsized version of the existing TD-BD-IGGD05K. Furthermore, in June 2013, TED will release a new IGBT gate driver that enables multiple connection of 1700V/1400A class IGBTs. TED plans to further expand the "inrevium" lineup of IGBTs in the future.
