Gate Driver Boards
Gate Driver Modules for IGBTs, MOSFETs and SiC FETs
Gate Driver Boards are complex blocks that interface power switches with the controller. In other words, their basic function is to provide isolation between high voltage circuit and low voltage controller. Furthermore, they also level shift drivers output to source/emitter ground in high side applications. In addition, each type of power switch requires different levels of output voltage and current and are exposed to application-specific risks such as high dv/dt and short circuit conditions.
There is also a low propagation delay requirement for high frequency switching that vary depending on the topology of the circuit and the switch being used. So, all available gate driver boards provide adequate features and functionality that cover most applications and devices such as IGBTs, MOSFETs, and Silicon Carbide (SiC) FETs. In conclusion, these gate driver boards are equipped to help you drive your switching circuit with ease and flexibility in all power switching applications.
