Infineon Technologies CoolGaN™ 600 V eval board

EVAL_1EDF_G1B_HB_GAN is a 600 V gallium nitride (GaN) half-bridge evaluation board that enables easy and rapid setup and test of CoolGaN™ transistors. The generic topology can be configured for boost or buck operation, pulse testing, or continuous full-power operation. Test points provide easy access to connect signals to an oscilloscope to measure the switching performance of CoolGaN™ transistors and gate drivers. This board saves the user from designing their own gate driver and power circuit to evaluate GaN transistors.

The half-bridge circuit board features a single PWM input intended for the connection of a 50 Ω pulse generator.

Key features

• Simple GaN half-bridge with dedicated GaN driver ICs
• Capable of multi-MHz switching frequencies
• Zero reverse-recovery: can shift between hard- or soft-switching
• GaN transistors feature top-side cooling for high power dissipation

Additional features

• Easy setup and use
• Multiple configurations possible
• Evaluate high-frequency capabilities of GaN
• Evaluate waveforms with low ringing, overshoot, EMI
• Enables easy evaluation at multi-kilowatt power levels

Applications

• Power Supply
