Abstract
A system made of a custom designed heat flow sensor, a thermo-electric heat-pump, and a microcontroller based control board is presented for the measure of the power losses in power switches, e.g. MOSFETs or BJTs, operating in dynamic repetitive regime. The heat-flux sensor consists of two highly linear proportional to absolute temperature (PTAT) CMOS sensors. The thermoelectric module holds the case of the device under test at ambient temperature, so that heat entirely flows through the calorimeter. As the dissipated power measurement relies on the measurement of a heat flow, the apparatus is particularly suitable, and provides reliable results, in fast switching devices, regardless of the switching frequency, thus overcoming the problems associated with direct electrical measurements.
