Magnetic Flux Signal Simulation with 16-channel Sensor Array to Specify Accurate IGBT Current Distribution
CIPS 2016 International Conference on Integrated Power Electronics Systems, Mar 8-10, 2016, Nuremberg, GermanyCurrent crowding of IGBT and power diodes in a chip or among chips is a barrier to the realization of highlyreliable power modules and power electronics systems. Current crowding occurs because of stray inductance imbalance, difference of chip characteristics and temperature imbalance among chips. Although current crowding among IGBT or power diode chips has been analyzed by numerical simulation, no sensor with sufficiently high special resolution and fast measurement time has yet been developed. Therefore, we developed a 16-channel sensor array and demonstrated IGBT current distribution imaging. By using the developed simulation method for the sensor array, the accuracy of the magnetic flux signals was confirmed. In future work, we will apply the simulation method to specify the IGBT current distribution corresponding to the structure of bonding wire and other wiring
Observation of the formation of anisotropic silver microstructures by evanescent wave and electron microscopy
Using a well-known galvanic displacement reaction, ~25–40 μm long silver ribbons grown after mixing ~50 nm copper particles with AgNO3 solution were observed as a function of Ag+ concentration and their growth was characterized in real-time and in situ by evanescent wave (EW) microscopy. At low Ag+ concentration, chain-like structures consisting of both Ag and Cu were observed. When the sequence of mixing these two reactants was reversed, different Ag microstructures (platelets and dendrites) were formed and were also characterized by EW microscopy. Dependence of the morphology of all these microstructures on silver ion concentration was determined by EW microscopy in conjunction with scanning and transmission electron microscopy
