  • Galvanic isolation for IGBT-Driver

    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

  • Reduce IGBT Gate Drive Design Costs and Space

    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.

  • IGBT Power Losses in Induction Heating Applications

    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

  • Using NEC Optocouplers as Gate Drivers in IGBT and Power MOSFET Applications

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

  • Expanding the Safe Operating Area of Polypropylene Dielectric IGBT Snubber Capacitors

    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

  • Comparing the Incomparable: Understanding and Comparing IGBT Module Datasheets (.pdf)

    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

  • Re: What Kind of Transistor?

    Most of the schematic circuit diagram show IGBT like the one you have presented. But the actual standard symbol has an inclined line between collector and emitter.

  • Re: Grid Connected PV System

    dear umer i am an automation engineer ,after the googling i got the information which i will like to share with you. Operating a renewable energy system in parallel with an electric grid requires special grid-interactive orgrid tie inverters (GTI). The power processing circuits of a GTI are simil...

  • Re: Converter

    Diode looks acceptable. Since you have changed the design from a 20Vdc on your schematic to a non-isolated 240Vac rectified (340Vdc?) power source, the IGBT and opto-isolator WILL be absolutely necessary. This information should have been part of your original post. The spec sheet and application...

  • Re: IGBT Dimming ??

    IGBT or FET based dimming has been around for quite a while. Unlike the posted schematic the circuit is usually realized by using 2 devices arranged in anti-series. The main reason to use this over conventional triac dimming is for capacitive loads such as electronic low-voltage lighting were reve...

  • Re: Vibration Transducers for Driving Simulation

    Here is a sketch of a home made vibration transducer. I do not have time now, to cover the details. This works. If you think you may want to play with this Idea, I will send you the IGBT that would do the job. and a schematic and more detailed construction info. I also have the transformer but it is...

  • Re: Power Supply Question...

    Actually, Cnpower had the same recommendation as StandardsGuy. I have a couple controllers on my desk that are rated 100A continuous, 300A peak. They will produce voltages from 0-48. Control over output is as described by cnpower: a very low-current circuit providing PWM switching of big transis...

The drive when inspected physically damaged its IGBT module of only one phase. The drive was replaced with

  • A New Gustometer for Taste Testing in Rodents

    In recent years, to circumvent the interpretive limitations associated with intake tests commonly used to assess taste function in rodents, investigators have developed devices called gustometers to deliver small volumes of taste samples and measure immediate responses, thereby increasing confidence that the behavior of the animal is under orosensory control. Most of these gustometers can be used to measure unconditioned licking behavior to stimuli presented for short durations and/or can be used to train the animal to respond to various fluid stimuli differentially so as to obtain a reward and/or avoid punishment. Psychometric sensitivity and discrimination functions can thus be derived. Here, we describe a new gustometer design, successfully used in behavioral experiments, that was guided by our experience with an older version used for over 2 decades. The new computer-controlled gustometer features no dead space in stimulus delivery lines, effective cleaning of the licking substrate, and the ability to measure licking without passing electrical current through the animal. The parts and dimensions are detailed, and the benefits and limitations of certain design features are discussed. Schematics for key circuits are provided as supplemental information. Accordingly, it should be possible to fabricate this device in a fashion customized for one’s needs.
