Navitas Semiconductor NVE107C 650V Bi-Directional GaN Eval Board

Navitas Semiconductor NVE107C 650V Bi-Directional GaN Eval Board provides significant flexibility for applications such as AC/AC matrix inverters, onboard chargers, and solar inverters. The test board enables the implementation of various test circuits based on the PWM sequencing and power connections. The NVE107C board comprises a power stage using two NV6427 bi-directional GaN switches in a half-bridge configuration, and a Navitas NV1702 IsoFast™ isolated dual-channel GaN driver drives the bi-directional switches. The NV6427 switches can block voltage in both directions to reduce the active chip and PCB footprint areas. The NVE107C eval board from Navitas operates with a nominal 12V auxiliary voltage supply, which powers four onboard isolated power supplies and the primary side of the two NV1702 isolated GaN drivers. Each isolated power supply features a 1:1 turns ratio, resulting in four isolated 12V rails on the secondary sides of the NV1702 ICs. The NV1702 internally regulates this voltage to offer a nominal 6.2V gate drive for the bi-directional switches.
