Full Digital Control Boards for IGBT Full-Bridge Switching Converters

On the field of thermonuclear fusion research, the need to implement coil systems supplied to perform local controls of magnetic fluxes or to generate rotating magnetic fields has grown in the past few years [1]. Tens of coils, each one able to produce up to tens of millitesla on a surface of hundreds of square centimeters, have to be independently fed by converters rated for powers of hundreds of kilowatts and bandwidth in the order of hundreds of hertz.
