The EVAL_HB_ParallelGaN is an test platform for design engineers who want to investigate parallel operation of Infineon CoolGaN™ to reach higher power levels in their designs. It is possible to check dynamic and static current sharing of individual devices in parallel configuration up to MHz level. The board also makes a good reference for PCB layout practices to achieve trouble-free operation with extremely fast GaN devices. The board is designed with isolated control and high/low-side driver power supply and drivers provide negative voltage to the gates during off-time to minimize the risk of shoot-through currents due to high dV/dt. A heatsink with insulating thermal pad may be attached to the devices if continuous operation at high power is desired. Gate common-mode inductors included to prevent coupling through the source terminals of the devices that might lead to oscillations. This system solution is available as Hardware Board or Reference Design.
