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...

Transformer-less Unified Power Flow Controller

IntroductionThe ability to store and shift electrical power over time is becoming more important as economies increasingly adopt renewable power sources. Meshed AC power grids have limited controllability and cannot effectively handle congestion of key transmission lines during sporadic peaks and valleys of input power, such as that produced by solar...
