Abstract |
Given the wide variety of available
switching devices (GTO, MOSFET, IGBT, MCT,
.....) and the range of switching modes used by
converters (hard and soft switching), it is very
difficult for power electronic designer to have a
clear view of the real capabilities of each
component and to choose the best one for a
particular use.
Since few years, EEPS Department works on
power losses measurement and metrology for
power component. A test machine
(SAEP [4]) has been built and measurements
problems have been resolved. The device
presented here is derived from this machine,
simplified and adapted to have specified tool. This paper presents methods for evaluating power
electronic components, driving circuit and all the
environment of active components in various
operating conditions. All of them are real ‘one shot
test’. The advantages of this technique is that the
energy consumption is very low, not destructive for the component, and each parameter could be
adjusted as independently as possible. |
