Non-destructive current measurement for surface mounted power MOSFET on VRM board using magnetic field probing technique

Abstract

This paper proposes nondestructive current measurement for surface mounted power MOSFET on VRM board using the micro-magnetic probing technique to facilitation discussion of the self-turn-on phenomenon. A notable feature of the proposed technique is that the sensor part is much smaller than that of conventional methods because this method measures the… (More)
