   ACCURATE SWITCHING ENERGY ESTIMATION OF WIDE BANDGAP DEVICES USED IN CONVERTERS FOR AIRCRAFT APPLICATIONS
By Bernardo COUGO, Henri SCHNEIDER, Thierry MEYNARD [View]
[Download]

Abstract: This paper describes a method which precisely estimates switching losses of fast power semiconductors. In this method, no transistor current is measured and, consequently the switching behavior of the transistor is not changed by the measurement system. By two different measurement modes, turn-off and turn-on losses can be estimated separately, which is necessary to precisely design isolated DC/DC converters used in aircrafts. The proposed switching loss measurement method is explained and experimental results on Silicon Carbide MOSFETs verify its operation and accuracy.

   DC-bias current measurement in high power AC grids
By Radoslaw NALEPA, Filip GRECKI, Magdalena OSTROGORSKA, Pawel ALOSZKO, Janusz DUC [View]
[Download]

Abstract: Solution dedicated to measurement of small DC-bias current, being a part of large AC current inpower grids, will be discussed in this paper. Ratio of AC/DC currents reaches 15000:1 or more. Suchlarge ratio represents significant challenge in terms of accurate measurement of the DC current in thepower grids.

   New applications in power electronics for highly integrated high-speed magnetoresistive current sensors
By Simon SCHERNER, Rolf SLATTER [View]
[Download]

Abstract: The usage of magnetoresistive current sensors is increasing steadily in the field of power electronics.Sensors must not only be accurate and dynamic, but must also be compact and robust. An integratedSMT magneto-resistive current sensor as well as a 2 MHz bandwidth THT current sensor isintroduced. Various future applications from the wide field of power electronics are shown that openup new possibilities in the fields of industrial automation, electro mobility and more electric aircraft.

   Parallel Chamber Calorimetric Concept
By Lassi AARNIOVUORI, Antti KOSONEN, Markku NIEMELA, Juha PYRHONEN [View]
[Download]

Abstract: A new type of a calorimetric measurement system concept for drives measurements based on open- and balance-type calorimeter is introduced and practically verified. The calorimetric concept with two parallel chambers is used to obtain the losses of the commercial frequency converter. The main advantage of this concept is the measurement rate of different operating points compared to the standard open- and balance-type calorimeter, because the main and balance test are carried out at the same time.
