16-Channel micro magnetic flux sensor array for IGBT current distribution measurement
Current crowding of IGBT and power diode in a chip or among chips is a barrier to the realization of highly-reliable power module. The author developed and demonstrated 16-channel flat sensitivity sensor array for IGBT current distribution measurement. The sensor array consists of tiny-scale film sensors with analog amps and shield case against noise.
