Isolated Igbt Gate Driver Evaluation Platform

The gate drive evaluation platform gdev was designed to demonstrate the continuous operation of littelfuse sic power mosfets and diodes in a half bridge configuration.

Isolated igbt gate driver evaluation platform.

Isolation robustness and higher power density is realized by integrating the isolator with a key power component. Iso5852s high cmti 2 5 a and 5 a reinforced isolated igbt mosfet gate driver with split outputs and active protection features datasheet rev. In addition it provides a well defined testing environment for evaluating and comparing the performance of various driving board designs as well as driver ics. Isolated gate drivers enable low voltage microcontrollers to safely switch high voltage power transistors on and off.

Safe switching of high speed silicon carbide sic and gallium nitride gan transistors places an extra requirement on isolated gate driver ics. Evaluation driver board for primepack modules up to 1200v using a coreless transformer single channel driver replaced by 1ed020i12 f2. Isolated igbt gate driver. The infineon eicedriver is offered as industrial and automotive qualified products.

This design allows performance evaluation of the iso5852s in 3 phase inverter incorporating 1200v rated igbt modules of current ratings ranging from 50a 200a. The integrated high speed isolated gate driver. Stgap isolated gate drivers are extremely flexible as they provide a large number of parameters that can be adjusted to best match the selected mosfet or igbt and system requirements. These isolated drivers incorporate the most important key features and parameters for mosfet igbt igbt modules sic mosfet and gan hemt driving.

Our isolated gate drivers are available in basic functional and reinforced isolation and accept a low power input from a controller ic to produce the appropriate high current gate drive for a mosfet igbt sic or gan power switch. The tida 00195 reference design consists of a 22kw power stage with ti s new reinforced isolated igbt gate driver iso5852s intended for motor control in various applications. Evaluation board for 1ed020i12 bt galvanic isolated single channel igbt driver ic with ct technology for 600v 1200v igbts. Some of the important functionality and performance evaluated are short circuit protection using desat detection soft shutdown effectiveness of.

Current and temperature sense minimizes igbt sic stress during faults. High common mode transient immunity cmti. Integrated galvanic isolation and low on resistance drive transistors provide high charging and discharging current low dynamic saturation voltage and rail to rail gate voltage control. The gd3100 is an advanced single channel gate driver for igbts sic.
