Drive transformers for IGBTs - insulation voltage up to 500 Vrms
In recent years, power electronics has had a decisive impact on the generation, distribution and conversion of electrical energy. Modern semiconductors enable fast and safe control and conversion of electrical energy with low losses. Key factors for progress in this area are shutdown power semiconductors such as IGBTs (insulated-gate bipolar transistors), MOSFETs (metal-oxide semiconductor field effect transistors), and GTO (gate-off thyristors). VAC products are an important factor in maintaining the efficiency and safety of semiconductor switching and low-loss power transmission.
Higher switching frequencies, higher blocking voltages and switching powers affect how semiconductors are activated and controlled, enabling safe and simple switching. The drive transformer ensures current separation while also providing switching signals and/or energy to the semiconductor drive circuitry.
