SN6505B: Topologies selection of Isolated DC/DC bias supply for IGBT gate drive

Tool/software:

Hi,

For inverter and isolated gate driver bias supply architectures, such as Fly-buck,LLC,Push-Pull.

Which topology is more appropriate, consider the cost, EMI, CMTI issue, pcb area etc.

Add, Whether the noise of the LLC topology is higher in the low frequency band of EMI.
