Usually, an IGBT (Insulated Gate Bipolar Transistor) is described in the following way: "An IGBT is a combination of a field effect transistor and a bipolar transistor where an N-channel FET controls a bipolar transistor". Although this sentence describes the basics very well, in the case of IGBT...

The ACPL-337J is an advanced highly integrated gate drive optocoupler, designed to ISOLATE, DRIVE, PROTECT and FEEDBACK the IGBT's operational status. It has a rail-to-rail output that can deliver 4A of maximum current capable of driving high power IGBT directly....

IGBTs with blocking voltages of about 1200 V are widely. used in single-ended induction heating applications. During. turn-off, the high voltage impressed across the IGBT. together with its residual current cause considerable. turn-off losses. During the on-state of the IGBT, the power. lost due...

Reviews the characteristics and technical requirements of using an NEC high speed optocoupler to gate drive an IGBT or Power MOSFET....

Important developments of IGBT's (Insulated Gate Bipolar Transistors) in recent years have been focused on increasing power handling capability and increasing reliability including short circuit tolerance. Snubber capacitors have also undergone changes in construction enabling increased power...

This might sound somewhat overdone but comparing IGBT modules using datasheets is. not as easy at is might appear. A rough comparison can, of course, be made using the. component blocking voltage (VCES, e.g. 1200V) and the nominal current. (ICnom = 100A, 200A...). On closer inspection, however...

...if catastrophic failures like IGBTs short circuit induce higher energy power into the optocoupler. This paper will discuss the impact of unprotected IGBT destructive tests on the insulation barrier of an Avago gate drive optocoupler....

The demand for portable low cost welding machines, especially in developing countries, is increasing. In the Manual Metal Arc and Tungsten Inergt Gas types, in power range from 1,5kW up to 5kW, discrete IGBTs and MOSFETs are broadly used. Mostly, these machines use hard switching current mode PWM...

This paper addresses various applications where NEC/CEL optocouplers offer galvanic isolation for driving MOSFET / IGBT devices in industrial applications including general-purpose inverters, AC servos power switching, home appliances and motor control applications....

...driver is normally in the form of a power transistor. This can be a bipolar transistor, MOSFET or an Insulated Gate Bipolar Transistor (IGBT). In some small Brushless DC motor or stepper motor applications, the MOSFET driver can be used to directly drive the motor. For this application note, though...
