IGD515EI

MEDIUM/HIGH-POWER SINGLE CHANNEL UNIVERSAL DRIVER CORE

Reliable, highly approved technology

For 1200V, 1700V and 3300V IGBTs, fiber-optic interface

Industry standard high-power IGBT gate drive unit since 1996

Short Description

The IGD515EI intelligent gate drivers are highly approved single-channel drive components for IGBTs. They were developed specifically for the precise and reliable driving and protection of high-power modules, high-voltage modules, series and parallel circuits.

The 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.

Special logic functions allow the implementation of reliable series circuits with IGBTs. The drivers support 2-level, 3-level and multilevel converters.

Gate driving with a positive and negative control voltage (±15V) allows reliable operation of IGBT modules of any size from any manufacturer. Thanks to the great interference immunity attained by means of the negative gate voltage, a number of IGBT modules can be connected in parallel without the user having to worry about parasitic switching operations or oscillations. The IGD515EI series contains an overcurrent / short-circuit protection circuit, a power-supply monitoring function, a status acknowledgement, a mode for brake operation as well as a mode for series and parallel circuits.

The driver core is optimized to match various IGBTs and applications from 100A / 1200V to 1000A / 1700V and beyond.
