Pb-Ge-Te-Compounds for Thermoelectric Generators or Peltier Arrangements

Executive Summary Thermoelectric devices convert heat into electricity. Conversely, if direct current is applied, heat will be transported from one side to the other (Peltier arrangement) and the device can also act as a heat pump. While some applications exist today, more efficient thermoelectric materials are needed to be practical for a broader...

High Efficiency Power Transistor Gate Drive

IntroductionGate-drive technology is traditionally an open-loop passive method that has no real-time control of a semiconductor power device’s switching speed, overshoot, and switching power losses. The technology is unreliable and cannot be optimized over different operating voltages and current conditions. It suffers high transient overshoots...
