产品描述

 

CTR-GU-HD Family of Intelligent IGBT Gate Unit is specifically developed for driving the heavy duty IGBT modules rated 3300V and 4500V. This gate unit product adopts programmable intelligent chip, which makes it possible to flexibly pre-set the protection threshold values, so that the performance and reliability of the converter is greatly improved. This gate unit product is now widely used in fields of high power converter and the main transmission system of the railway on-board vehicles.

 

 

  • The CTR-GU-HD series of Intelligent IGBT Gate Unit is used for driving 4500V and 6500V heavy IGBT modules, including the CTR-GU-4502 and CTR-GU6502 models. They are composed of two parts: the gate unit board and the gate adapter board. The gate adapter board is mounted on the IGBT module and the gate unit board is installed separately.
  • The CTR-GU-HD series of Intelligent IGBT Gate Unit adopts four kinds of gate resistance drive circuit. Through the control of intelligent chip, it can achieve:
  • (A) During the IGBT opening period, the opening gate resistance Rg - on is input. Turing the closing period, the normal turn-off gate resistance is input. After the end of closing period, the enhancing closing gate resistance Rg- off2 is input to enhance the anti-interference performance;
  • (B) When it detects the IGBT short-circuit fault, the fault closing gate resistance Rg - off3 of higher resistance value is input to ensure that the short-circuit fault is the most reliable and safe.
  • The CTR-GU-HD series Intelligent IGBT Gate Unit adopts the unique threshold curve short-circuit fault identification technology, which can detect the Uce of the whole process of IGBT conduction. Through the Uce precision matching of the different stages of the IGBT opening process, it reduces the dead zone of protection to a large extent, which realizes the effectiveness, timeliness and high degree of unification of the short circuit fault protection.
  • The CTR-GU-HD series of Intelligent IGBT Gate Unit can directly drive two shunt-wound 4500V / 1200A or 2 shunt-wound 6500V / 600A IGBT modules;
  • The CTR-GU-HD series of Intelligent IGBT Gate Unit are equipped with a unique gate adapter board that effectively eliminates the gate breakdown of the IGBT, limits and reduces the voltage spike of closed Uce at short-circuit and significantly improves the IGBT reliability and security.
  • The CTR-GU-HD series of Intelligent IGBT Gate Unit adopts DC24V single power supply mode.
  • The CTR-GU-HD series of Intelligent IGBT Gate Unit have a built-in high-voltage isolated voltage-stabilized source, without the need of extra configuration of isolated power supply.
  • The CTR-GU-HD series of Intelligent IGBT Gate Unit has short circuit protection, over-temperature protection and power supply under-voltage protection.
  • The CTR-GU-HD series of Intelligent IGBT Gate Unit is equipped with a PT100 or PT1000 temperature detecting element interface.
  • The CTR-GU-HD series of Intelligent IGBT Gate Unit has excellent electromagnetic compatibility and dust-proof, damp-proof, quake-proof and anti-shock functions, which is suitable for using in harsh working conditions.
