How to select the appropriate IGBT for circuit design

How to select the appropriate IGBT for circuit design




What is IGBT? It works What is this? Why do we have to choose IGBT? What are its advantages? A series of questions to throw, in the March 5 15th Annual International IC-China Conference & Exhibition (IIC-China2010), the International Rectifier Corporation (InternationalRectifier, referred to as IR) the best explanation given by the company.



IGBT (InsulatedGateBipolarTransistor), insulated gate-type power tube is determined by BJT (bipolar transistor) and MOS (insulated-gate type FET) a composite full-controlled type voltage-driven power electronic devices. Applied to AC motor, power inverter, switching power supplies, lighting circuits, traction drive and other fields.



IGBT is a strong current, high-pressure applications and fast terminal equipment with the natural evolution of the vertical power MOSFET. As the realization of a high breakdown voltage BVDSS the need for a source-drain channel, and this channel does have a high resistivity, resulting in power MOSFET with RDS (on) the characteristics of a high value, IGBT power MOSFET to eliminate the existing of these The main disadvantage.



And, IGBT applications is very extensive, not only the driver can be used for home appliances such as washing machines, air-conditioning systems, etc.; industrial motor drive; induction heating; sine wave inverter; and in lighting, such as high-voltage gas discharge lamp applications is also very appropriate.



IR Asia, Pan Dawei, vice president of marketing, said: "We have been in order to save the global energy responsibility, as a leader in power management innovation, we hope that China and engineers to share our energy-efficient power management solutions, including GaN technology platform. "



In addition, IR in this exhibition will showcase their latest products and platforms, including GaN power devices platform GaNpowIR. In addition, will showcase the latest release of the X-Phase and DirectFETMOSFET chipsets, SupIRBuck family of integrated voltage regulators and for the AC-DC power supply SmartRectifierIC, as well as for electrical iMOTION integrated design platform. Other display products include applications for high-reliability DC-DC converters and modules, as well as for the automotive, lighting, D audio benchmarks various fields such as MOSFET, IGBT and high-voltage IC.
