IGD515EI single-channel intelligent gate drivers have been developed specifically for the precise and reliable driving and protection of high-power and high-voltage modules, in series and parallel configuration.
Drive information and status acknowledgement are transmitted via external fiber-optic links. The drivers contain an integrated DC/DC converter with a high-isolation test voltage.
Specific logic functions facilitate reliable series implementation. The drivers support 2-level, 3-level and multilevel converters.
Positive and negative control voltage (±15 V) gate driving allows IGBT modules of any size from any manufacturer to be operated. The negative gate voltage results in a high degree of immunity to interference, therefore several IGBT modules can be connected in parallel without the user having to worry about parasitic switching or oscillations. IGD515EI drivers feature: overcurrent / short-circuit protection; power supply-monitoring; status acknowledgement; a mode for brake operation; and a mode for series and parallel circuit design.
The driver core is optimized to match various IGBTs and applications from 100 A / 1200 V to 1000 A / 1700 V and beyond.
