EVAL-1ED3121MX12H Evaluation board for 1ED3121MX12H - 2300 V, 5.5 A, 5.7 kV (rms) single-channel isolated gate driver
The EVAL-1ED3121MX12H is in half-bridge configuration with two gate driver ICs (1ED3121MU12H) to drive power switches such as IGBTs and SiC MOSFETs. An additional gate driver IC is used for isolated over-current feedback signal from high voltage side to logic control side. Fast operational amplifier is used as comparator for over-current detection. This board is best suited for double-pulse testing.
1ED3121MU12H belongs to the EiceDRIVER™ Compact 1ED31xx family (X3 compact family). 1ED3121 offers separate sink and source output, accurate and stable timing, active shutdown to ensure a safe IGBT off-state in case the output chip is not connected to the power, short-circuit clamping to limit the gate voltage during short circuit. The driver can operate over a wide supply voltage range, either unipolar or bipolar.

You will have a glimpse of the different gate driver technologies available at Infineon and their benefits.
For a better understanding we will take a look at the optimization of external gate resistors to drive MOSFETs in a given application.
With this training, you will learn how to calculate a gate resistance value for an IGBT application, how to identify suitable gate driver ICs based on peak current and power dissipation requirements, and how to fine-tune the gate resistance value in laboratory environment based on worst case conditions.
Silicon Carbide MOSFETs bring a lot of opportunities to power electronics. However, how to achieve sufficient system benefits by using Silicon Carbide MOSFETs with suitable gate drivers? This training helps you to learn how to calculate a reference gate resistance value for your Silicon Carbide MOSFET; how to identify suitable gate driving ICs based on peak current and power dissipation requirements; and how to fine-tune the gate resistance value in laboratory environment based on worst case conditions.
