For real-time monitoring of the on-resistance of a power transistor, the voltage and current should be measured during the switching operation. When the voltage waveform is measured, the amplifier inside the measuring oscilloscope may be distorted if the range of the measurement channel is not set wide enough to measure both on-state and off-state voltage levels, resulting in failure to accurately...
The prognostics and health management (PHM) of airborne equipment plays an important role in ensuring the security of flight and improving the ratio of combat readiness. The widely use of electronics equipment in aircraft is now making the PHM technology for power electronics devices become more important. It is the main circuit devices that are proved to have high failure rate in power equipment...
