EVAL-1ED3491MX12M
Evaluation board for 1ED3491Mx12M - 2300 V, 9 A, single-channel flexible isolated gate driver with active Miller clamp, adjustable DESAT and Soft-off
The EVAL-1ED3491MX12M is in half-bridge configuration with two gate driver ICs (1ED3491MU12M) to drive power switches such as IGBTs and SiC MOSFETs. The switch type can be freely chosen. The board has a size of 85 x 55 x 15 mm without any power switch assembled. TRENCHSTOP™ IGBT IKW40N120H3 or CoolSiC™ MOSFET IMW120R030M1H is recommended. This board is best suited for double pulse testing and evaluation. The low voltage supply interface can be controlled by a pulse generator, a microcontroller or any other suitable digital circuit. The evaluation board has a power supply for the primary and secondary sides implemented.

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.
