Active gate drivers

Switching power supplies have become the norm in almost all electronic systems. The switchers' excellent line and load regulation, high conversion efficiency, and compactness all contribute to their popularity. Low-loss power MOSFETs and IGBTs (insulated-gate bipolar transistors), coupled with low-drop rectifiers, are at the heart of these switching supplies. The subject of driving MOSFETs/IGBTs to their highest possible frequencies at the highest possible power levels, still providing protection, is multi-dimensional and requires knowledge of MOSFETs and IGBTs as well as circuit theory and how it applies to this discipline. Many topologies in high voltage converter, inverter and matrix converter applications require special techniques to drive MOSFETs and IGBTs
