- Is Your IGBT Gate-Driver Power Supply OptimizedPDF, 115 Kb, 档案已发布: Mar 12, 2015
Insulated Gate Bipolar Transistors (IGBTs) are used in high current three-phase AC motors. This application report discusses the theory and requirements of gate-drive power supply for IGBTs. It also discusses the isolation requirements and calculation of correct amount of IGBT drive power. - AN-2292 Designing an Isolated Buck (Fly-Buck) Converter (Rev. C)PDF, 870 Kb, 修订版: C, 档案已发布: Dec 17, 2014
In many applications, one or more low-cost, simple to use, isolated power supplies working from input voltages up to 100 V are needed. Traditional solutions use flyback converters to generate this bias supply. Flyback designs typically utilize asymmetric transformers turns ratios for primary and secondary power windings, with an optocoupler and reference, or an auxiliary winding for feedback regul - Fly-Buck(TM) converter provides EMC and isolation in PLC applicationsPDF, 201 Kb, 档案已发布: Jan 29, 2015
