— Large area die-attach defects have been shown to increase the thermal impedance of power semiconductor devices. The changes in thermal performance are simulated and measured in the silicon die using one, two, and three dimensional methods. Experimental measurements for devices with various levels of die-attach void growth are presented. This data is then(More)
A matrix converter and variable-speed diesel generator are integrated to create a three-phase utility power supply. The matrix converter is designed to meet tight harmonic and transient response requirements while allowing variable voltage and frequency input from the generator’s permanent magnet alternator. This enables the generator to provide stable(More)
